Hi Thorsten, hi Greg,
6.7.9 + some bcachefs upgrade/downgrade fixes included in 6.7.11 works okay. 6.7.11 fails. Two repeated attempts failed with a dmesg like this:

Could that be related to the following issue?
* Hibernate stuck after recent kernel/workqueue.c changes in Stable 6.6.23 @ 2024-04-02 8:08 Linux regression tracking (Thorsten Leemhuis)
https://lore.kernel.org/regressions/ce4c2f67-c298-48a0-87a3-f933d646c73b@lee...
However I did not find above work queue related error messages in the dmesg in the bug tracker bug report mentioned there:
https://bugzilla.kernel.org/show_bug.cgi?id=218658
If really needed I could do a bisect, but it would take a while until I can take time to do it.
Best,
