A similar report was done in SuSE https://bugzilla.suse.com/show_bug.cgi?id=1129258 Can you check if hte issue ist still present with a more recent kernel, ideally test up to 5.8.7-1 in unstable. If the issue is still present, it might be woth reporting it directly upstream to the linux-...@vger.kernel.org list. Regards, Salvatore
Bug#959232: linux-image-5.5.0-2-amd64: system freeze after suspend-to-ram: potentially IRQ-related issue
Package: src:linux
Version: 5.5.17-1
Severity: normal
Dear maintainer,
Occasionally my system freezes after waking up from suspend-to-ram.
More precisely, the KDE lock screen appears, I can type my passphrase,
but then the screen just stays black leaving me movable mouse. I
neither can switch to a virtual terminal (Strg+Alt+F1 etc.) nor kill
the session with SysRq+K. Rebooting with SysRqs still works though.
Investigating the issues in the kernel logs reveals a message
indicating a NULL ptr derefererence in the kernel that is related to
IRQ (see below).
My device was in suspend-to-ram since yesterday so the attached log
includes all messages since I opened the laptop lid. It was generated
using:
journalctl -b-1 --dmesg --since today --quiet --no-hostname --grep
'^(?!iptables:)'
Such freezes happen about once a week and since I got the device (so
it also happened with older kernels).
The device is a Lenovo X1 Carbon 6th Generation with an Intel
i7-8650U with up-to-date BIOS running Debian Testing.
Any help is highly appreciated.
Best,
Maximilian
