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: [12164.210808] watchdog: BUG: soft lockup - CPU#1 stuck for 22s!
