Subject: Occasional crashes when resuming from software suspend
Date: Wed, 14 May 2025 10:34:59 +0200
Hello,

With Linux-libre 6.14.5-gnu (commit
300d29e69988caf23684f08effa51f621c7ec083), my laptop occasionally
crashes when resuming from software suspend: blank screen, does not
answer to pings, cannot switch ttys, etc. and hard shutdown is the only
way out.  /var/log/messages shows software suspend but does not contain
a single line corresponding to resuming:

This was fine with 6.14.4 (commit
3cdf7bec6b1caa808a7b498ea8ca4596ab1edfeb) and earlier versions.

What hardware do you see this on?

On my Thinkpad x260 with an Intel i5, resume stopped working for me in 6.1, and I'm still using 5.15. The failures are not deterministic for me. Sometimes it works.

I found scattered reports about this with no conclusive analysis, so I'm planning to replace the computer before 5.15 becomes unsupported.

It’s on an HP EliteBook Folio 1040 G3/80FA (from 2016).  It’s also
non-deterministic here.

I’ve been using suspend-to-disk more frequently lately, so I wonder if
it could be an aggravating factor.

Same problem with 6.14.6-gnu.
