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: [ 192.465064] r8169 0000:05:00.0 en1: Link is Down [ 193.246691] PM: hibernation: hibernation entry [ 193.622844] Filesystems sync: 0.097 seconds [ 193.623337] Freezing user space processes [ 193.627326] Freezing user space processes completed (elapsed 0.003 seconds) [ 193.627390] OOM killer disabled.

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@xxxxxxxxxxxxx/T/#u 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, -- Martin
