Public bug reported:
[ Impact ]
hirsute:linux 5.11.0-45.49 is not booting on several systems/instances.
The boot failure is caused at least in most of the cases by systemd
services failing to start. On a amd64 test VM the journald service times
out when it's configured to use any storage type (which is the default
config).
[ Fix ]
I was able to boot a VM with the following commit reverted:
327aa2137d989f278ece7e8e31c218dfb3416c35 - mm: filemap: check if THP has
hwpoisoned subpage for PMD page fault
[ Additional Info ]
On an affected VM, after a bit more than 1 hour after booting I get the
following soft lockup which helped identify a suspicious commit:
