Microsoft Surface Pro 8 and BSODs since a couple of month back

zbook · Jul 30, 2023

1) Please reinstall:

spvdport SoftPerfect Virtual Disk c:\windows\system32\drivers\spvdbus.sys

Name SoftPerfect Virtual Bus
Manufacturer KEG
Status OK
PNP Device ID ROOT\SCSIADAPTER\0000
Driver C:\WINDOWS\SYSTEM32\DRIVERS\SPVDBUS.SYS (, 97,43 KB (99 768 bytes), 2022-07-06 09:36)

2) Make a new retore point

3)Restart WDV with all customized tests except:

[ ] 0x00000004 Randomized low resources simulation.

Post a new querysettings and / or V2 into the newest post.

iorx · Jul 30, 2023

Hi!

Just curious. How did you or what made you suspect this driver?

I actually replaced SoftPerfect RAM-disk with ImDIsk since yesterday.
So a question here. Should I go back to SoftPerfect and do the above test, or keep ImDisk? I can also scrap it completely and run the machine with out it, let me know which way is the best.
Will do.
Last time I did this I encountered repated BSODs and then after a couple of them got offered to Restore from a restore point. Should I still use those settings? And, which drivers should be ?

(link for files and query settings in next post)

zbook · Jul 30, 2023

When you last had WDV on the misbehaving driver was identified in the debugging.

If the software has been completely uninstalled then it can no longer be a cause of BSOD.

iorx · Jul 30, 2023

I'll run like this then and WILL return my experience here either what the outcome is so we get a proper closure and resolution.
Can't thank you enough for this assistance. I hadn't went this deep-route in troubleshooting before with the WDV. I learned allot!

If you got time, could you point out where in which log, you found that spvdbus.sys was the misbehaving driver?

A device driver attempting to corrupt the system has been caught. This is
because the driver was specified in the registry as being suspect (by the
administrator) and the kernel has enabled substantial checking of this driver.
If the driver attempts to corrupt the system, bugchecks 0xC4, 0xC1 and 0xA will
be among the most commonly seen crashes.

Thanks! Found it in 072723-14984-01.dmp (I'm closing the folder share in a day or two)

In the dump analyze it mention this:
A device driver attempting to corrupt the system has been caught. This is
because the driver was specified in the registry as being suspect (by the
administrator) and the kernel has enabled substantial checking of this driver.
If the driver attempts to corrupt the system, bugchecks 0xC4, 0xC1 and 0xA will
be among the most commonly seen crashes.

Is it possible to see this, in the registry, if a drivers is suspected?

BTW. Still a stable machine!

zbook · Jul 31, 2023

1) Make a new restore point

2) Consider making free backup images and saving the images to another disk drive or the cloud

I'm not aware of methods to search the registry to confirm WDV C4 findings.

iorx · Jul 31, 2023

Celebrating the victory to soon I think...

And "no!", just BSODed.

This time I had allot running including a virtual machine in Hyper-V.

New V2 file in the share, MSP8-(2023-07-31_10-54-14).zip.
Should I repeat the last WDV, the one that had all but [ ] 0x00000004 Randomized low resources simulation. checked?

Answer to your bullets.

I do this on regular basis now.
Got a complete vhdx shadowcopy on a server locally.

iorx · Jul 31, 2023

Just went down as a "ton of bricks" in the middle och a Teams meeting...

V2 log added to the files. sp8-bsod

And... ImDisk is uninstalled now. Running without any ram-disk for the moment.

zbook · Jul 31, 2023

Please restart WDV with all customized tests except:

[ ] 0x00000004 Randomized low resources simulation.

If there is no immediate BSOD then run verifier /querysettings > post a share link into this thread using one drive, drop box, or google drive

For any BSOD post a new V2 share link into the newest post.

iorx · Aug 1, 2023

Just had a BSOD. What I had running: OpenVPN, Edge Dev (multiple profiles), Outlook, RDCman. New V2 files in the folder, MSP8-(2023-08-01_12-19-22).zip. And activating WDV again now.
A "pain in the but" is that Windows Search needs to reindex after every BSOD... machine is rather busy with this after.

It survived the reboot. Running with these settings until next BSOD.

zbook · Aug 1, 2023

The newest crash was on:

Tue Aug 1 05:06:40.889 2023 (UTC - 5:00).

This BSOD occurred without WDV.

Run WDV for approximately 48 hours with the current test settings.

iorx · Aug 1, 2023

I'll keep the settings until next BSOD. You mention 48h, should I revert/reset WDV after that even if I'm not experience a BSOD?
Are there any valuable logs from WDV while active or is it only usefull and add info to the dump-file in an event of a crash?

zbook · Aug 1, 2023

Continue using WDV for 48 hours in the background while you using the computer.

For any BSOD post a new V2 share link.

If there are no BSODs for 48 hrs and there are no major performance problems you can run it for an additional 24 hours then turn off the tool.

iorx · Aug 2, 2023

And this morning, I was not even working at the machine, it looks like it encountered a crash.

V2 log MSP8-(2023-08-02_10-34-58).zip, here: sp8-bsod

Microsoft GameInput was reconfigured right before the crash, or so it looks to me. Suspicious

.

Verifier still active.

I had a look at the dump, and this time it's ndis something that is mentioned.

Brgs,

The recommendation of 48 hours is completely arbitrary, that ballpark figure was based on experience of a few different analysts from a different forum. Some of the settings you're running Driver Verifier with are actually deprecated on newer builds so probably aren't actually even running. Additionally, you should actually be including a few Microsoft drivers for verification as well, notably: fltmgr.sys, ndis.sys, storport.sys and Wdf01000.sys.

iorx said:

Driver Verifier is only "useful" when it actually crashes, which is the purpose of the tool: inject verifier.sys into several driver stacks and then check for common bugs, if it encountered one, then it will crash with a Stop 0xC4 or a Stop 0xC1. The dump file should then point out the driver which is responsible for causing the crash. Microsoft has actually implemented something similar in their new WDF (Windows Driver Framework), in that they've added some exception handling code which will deliberately throw a bugcheck (Stop 0x10D) with lots of debugging information to make crashes very easy to debug.

iorx said:

I believe that this is simply referring to the driver verification list you specify when you start Driver Verifier. It should be available under the following registry value:

Code:

reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v VerifyDrivers

    This is NOT a break in NDIS.sys
    The most common causes of these types of breaks are hung/unresponsive miniport firmware,
    failed power transitions, or failing MiniportRestart.

This is one of those cases where enabling Driver Verifier with ndis.sys may have been useful. Unfortunately, this is also one of those cases where you will need to provide a full kernel memory dump and then hope that the system doesn't crash, otherwise the file will be overwritten.

The file should be available in the following path, please copy it to a .zip file and then upload it your OneDrive as you have with the other files.

Code:

%systemroot%\MEMORY.DMP

Additionally, could you please search for the following string using FRST:

FRST Registry Search
1. Click your Start button and type in cmd.
2.After you find the Command Prompt, right click on it and select Run as Administrator.
3. Copy and paste the following into the Command Prompt:

reg load HKLM\DRIVERS C:\WINDOWS\SYSTEM32\CONFIG\DRIVERS
4. Please download Farbar Recovery Scan Tool and save it to your Desktop.
Note: You need to run the 64-bit Version so please ensure you download that one.
5. Run FRST64 by Right-Clicking on the file and choosing Run as administrator.
6. Copy and paste d36e972-e325-11ce-bfc1-0 into the Search box and click the Search Registry button.
7. When the scan is complete a notepad window will open with the results. Please attach this to your next reply. It is saved on your desktop named SearchReg.txt.

I believe that the GUID is going to be part of a device instance key or something similar.

x BlueRobot · Aug 2, 2023

The bugcheck from yesterday was also network-related so there is certainly something within your network stack which is causing a problem. I suspect that it may be OpenVPN but let's wait until you've provided the MEMORY.DMP file so we can get more information.

iorx · Aug 2, 2023

Thank you so much for the elaborate answer here! I'll do my best here to follow up.

Added the MEMORY.DMP as "MEMORY-2023-08-02_1030.7z" from the crash 10:30 today (verifer did not have ndis checked). A 7z-archive.
And the FRST64 as "FRST64-2023-08-02_1653_SearchReg.txt"

I'll rerun the verifier now with previous settings specified plus the ndis driver.
I've also changed the kernel dump settings to "kernel memory dump" instead of "automatic".
Restore point created.

Should I unload the hive after the FRST64?
"reg load HKLM\DRIVERS C:\WINDOWS\SYSTEM32\CONFIG\DRIVERS"

Note. Historically I've had some problem with "Realtek USB GbE", to get a stable operation when that is active I've had to modify its power settings, "Selective Suspend". (the NIC in my eGPU, which is not attached at the moment). The machines only peripheral right now is a Bluetooth mouse.

Going for a reboot in a moment. Will reconnect here when I encounter next BSOD...

Thanks, it looks like your Intel network adapter was the one which was experiencing problems. It was in an hibernation state when the crash occurred so there is a possibly that it failed to wake from sleep, I'm curious to see if Driver Verifier will catch anything with ndis.sys being verified as well, but if it doesn't, then we can look at updating any network related drivers and booting into Safe Mode with Networking etc.

You could have left it as automatic, it will produce both Minidumps and a single kernel memory dump.

"reg load HKLM\DRIVERS C:\WINDOWS\SYSTEM32\CONFIG\DRIVERS"

As you've rebooted the machine, then the hive is probably unloaded now. I wouldn't worry about it though, the DRIVERS hive is dynamically loaded and unloaded by Windows when needed. It won't cause any problems with it remaining loaded.
