BSOD on Pool Import

[guenther-alka]

current Windows 11 Pro with Avast Antivir

- update from rc 10 to rc 11 (no reboot demanded)
- import pool -> BSOD (System Thread Exception not handled, 0x7E, see memory dump)
-> back to rc 10 vss3 (with initial VSS support): ok

Sounds like maybe new version didn't install, did you reboot?

I retried an update from rc10vss3 to rc11
This time I got an immediate BSOD (detected fatal error)

After reboot, I retried update from rc10 to rc11
This time installer runs through and I rebooted manually

After reboot:
zpool import -f winpool -> BSOD (System Thread..)

ok, now I had a BSOD with rc10vss3
Installed rc10 (no vss) and this works

I tried my Windows 11 VM with rc10vss3
Uodate to rc11 failed with an installation error, zfs not working
restarted rc11 installer again, zpool import worked.

I then tried to access the snap I made with rc10vss3 and got

Our QueryDeviceRelations(BusRelations) returns a list of devices (mounts) and one of them already had IoDeleteDevice() called on it, it does not like that.
