Hi, I am requesting help for a suspend/resume problem on a laptop since kernel 6.1. The laptop randomly goes in s2idle mode instead of deep. Resuming from s2idle is the problem, it would most often result in a black screen, magic keys don't work and there's no choice than a hard reboot. The cycles below are grepped from everything.log (using syslog-ng).

After removing the above parameter, i.e., the default, /sys/power/mem_sleep contains 's2idle [deep]'. I grant that 'deep' is the default suspend mode, though it does randomly go in 's2idle' on its own. /sys/power/state contains 'freeze mem disk'. After reverting to kernel 6.0.12-arch1, suspend/resume works normally, as it always did. I'm out of ideas for a fix, and would appreciate any clues.
