> Attaching the Journal, the initial crash can be seen at 12:31:54, lots going on there, but nothing root-causing this.
[ 3300.659129] WARNING: CPU: 1 PID: 65823 at drivers/gpu/drm/amd/amdgpu/../display/dc/gpio/gpio_service.c:315 dal_gpio_service_open+0x1b6/0x270 [amdgpu] This is the assertion you're hitting: https://github.com/torvalds/linux/blob/v6.12-rc4/drivers/gpu/drm/amd/display/dc/gpio/gpio_service.c#L315 Can you reproduce this at will? Is it tied to being docked? If so it might be related to HPD events coming in at the wrong time from the dock. We saw something similar that has been fixed in 6.11.y. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/gpu/drm/amd?h=linux-6.11.y&id=c2356296f546326f9f06c109e201d42201e1e783 If you can still reproduce this (at will) with 6.11.y and 6.12-rc4 please raise it upstream. At this point I'm not convinced that PSR is the perpetrator, but rather feels like a victim. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2085340 Title: Plenty of amdgpu backtraces post resume Status in linux package in Ubuntu: Confirmed Status in mesa package in Ubuntu: Confirmed Bug description: This is a very weird case: The GNOME session crashed 3 times today, the last time, it went to gdm, but then gdm did not recognize it was docked and suspended. I think the kernel needed two attempts to resume, it got suspended again after the first one; and it produced a whole bunch of back traces in dmesg.
