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.
