`kernel NULL pointer dereference` on USB-C dock disconnect & resume from sleep on 6.2.6 #253

Open MattF-NSIDC opened 1 year ago

MattF-NSIDC commented 1 year ago

This "freezes" the machine (can move mouse, but executing any command in an open terminal stalls, new terminal windows don't display a prompt, other programs locked up, can't access virtual terminals with e.g. CTRL+ALT+F3) and the only way to resolve is a hard shutdown with the power button. I need to hard reboot for this issue 3-4 times a day :sob:

This is reproducible 100% of the time (systemctl suspend or remove USB-C cable) on my Thinkpad T14 Gen3 (Intel) running 6.2.6-76060206-generic #202303130630~1681329778~22.04~d824cd4. I don't think it was happening last month, and my apt history log is telling me that I upgraded from 6.2.6-76060206.202303130630~1680814622~22.04~3850312 on April 18, which corresponds with when this started happening.

I believe that this bug report on kernel.org is the same issue: https://bugzilla.kernel.org/show_bug.cgi?id=217106. The address in the first line is always the same as well. Will 6.2.9 be available some time soon to hopefully resolve this issue?

Installed mainline 6.2.9 and was not able to reproduce the issue with a systemctl suspend or by disconnecting my USB-C cable! Huzzah :tada:
