Dear Kernel Team,
since linux 6.1.135-1 (linux-image-6.1.0-34-amd64) my system won't boot anymore due to a
regression in the upstream kernel.
The bug has been fixed upstream already:
https://lore.kernel.org/linux-raid/[email protected]/
And has been released in kernel 6.1.146:
https://lwn.net/Articles/1030359/
I recompiled the debian kernel (6.1.140-1) with that patch applied and
can confirm that it fixed the issue.
Technical details about my system:
* Two SATA SSDs combined as raid 1.
* Uses Intel VROC (fake-raid)
* Internal bitmap configured (required for the bug to be triggered)
Workarounds are to disable the internal bitmap or to not upgrade the
kernel for now.
Would you please release a new debian kernel for bookworm? And please
ensure that the upcoming trixie kernel includes the fix (I didn't check
if it already does).
Thanks,
Jörn
