Hi,
Recurring BSODs on first boot of the day since mid Oct. Reproducible with
26H2 enablement package (KB5121794), gone on 25H2. Summary of what I've
already ruled out below.
ENV
MSI Thin GF63 12VF (MS-16R8)
i7-12650H / 16GB / RTX 4060 Laptop + Intel UHD
SSD: Kingston OM8PGP4512Q-AI 512GB NVMe
BIOS: E16R8IMS.117 (flashed 21 Oct, was 10E from 2023)
Win11 Home 25H2 26200.9711 (current). Issue on 26H2 / KB5121794.
Dual boot Linux Mint 22.3, UEFI + GRUB, Secure Boot on
Disk 0: EFI 300M | C: 406.5G NTFS | Linux 47.85G | Recovery 1.03G | Recovery 21.13G
CONFIG (partly changed during dual boot setup)
BitLocker: fully decrypted, protection off
Hibernation: off (-> no Fast Startup)
Pagefile: was 0 MB until 16 Oct, now system managed
System Restore: was off until 16 Oct, now on
BIOS: VMD off, Fast Boot on, UEFI, SB on
WU: paused until 04 Dec, "get latest updates" off
TIMELINE
pre dual boot no issues, updates fine
post setup Windows Hello PIN lost (TPM related), re-enrolled
16 Oct 26H2 + Rainbow Six Siege -> 0x13A KERNEL_MODE_HEAP_CORRUPTION,
reproducible. Removing KB5121794 fixed it (matches Ubisoft advisory)
18 Oct cold boot, 25H2 -> 0xc0000218, hangs at 0%. 2nd boot OK.
chkdsk /scan clean (0 bad sectors), sfc repaired files,
DISM RestoreHealth OK, sfc rerun clean
19 Oct cold boot -> 0xc0000218 again (twice that day). 2nd boot OK
21 Oct cold boot -> 0x74 BAD_SYSTEM_CONFIG_INFO. 2nd boot OK.
Get-PhysicalDisk: Healthy/OK, wear 0, 25C
mdsched: no errors, sfc clean. PIN lost again after mdsched.
BIOS 10E -> 117 via USB (UEFI BIOS Update)
22-29 Oct 25H2 + new BIOS: clean cold boots every day
29 Oct KB5121794 reinstalled by WU
30 Oct cold boot, 26H2 -> 0x7A KERNEL_DATA_INPAGE_ERROR, hangs at 0%,
then Automatic Repair failed (SrtTrail.txt).
Booted on next try, removed KB5121794, back on 25H2
NOTES
- only on first boot after several hours powered off, warm reboots never crash
- all codes = disk read / registry hive load failing during boot
- BSOD hangs at 0%, volmgr 161 "Dump file creation failed" logged after each one
- clean shutdown logged before every crashed boot
- no disk/stornvme errors for the internal SSD in the System log
- Linux booted once in that period, didn't touch NTFS
- also seen on 26H2: UplayWebCore crashes, one Metro crash
- older minidump from 29 Sep (before dual boot) points to BEDaisy.sys (BattlEye)
- no overclocking/undervolting, stock settings
- laptop is 2+ years old, out of warranty
QUESTIONS
1. known issue with 26H2 / KB5121794 + NVMe on cold boot or dual boot setups?
2. can hibernation off / BitLocker decrypted / pagefile history conflict with 26H2?
3. how to get a dump when the BSOD hangs at 0%?
4. worth testing/replacing the SSD despite clean diagnostics?
5. cleanest way to block KB5121794 on Home until fixed?
