Bug ID: 215025 Summary: [amdgpu] Thinkpad A275 hangs on shutdown / screen does not turn on after reboot Product: Drivers Version: 2.5 Kernel Version: 5.15.2 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: bjo@nord-west.org Regression: No
My Thinkpad A275 hangs while going into suspend. The screen turned off, but it does not really enter suspend mode (according to journalctl it started suspending). Even after reboots the screen does not turn on again, I have to power off the Thinkpad and then power it on again. The issue did not exist with 5.14.x.

--- Comment #2 from Bjoern Franke (bjo@nord-west.org) --- Tested 5.14.16 - ok Tried 5.15.0 and 5.15.1 -> don't even boot, the first 3 lines look misarranged.
I will try to bisect between 5.14.16 and 5.15.2.
