Title:
amdgpu: [powerplay] Failed to send message errors
Status in linux package in Ubuntu:
Confirmed
Bug description:
When using multiple monitors with amd gpus (actually, 2 amd gpus in my
case), I get a many-seconds graphics lockup after the login screen,
while trying to switch to the desktop view.
In dmesg I see many messsages about "amdgpu: [powerplay] Failed to
send message errors".
This looks like a known deadlock issue in some 5.x kernels, but is
supposedly fixed in 5.6-rc2.
See discussion here:
https://bugs.freedesktop.org/show_bug.cgi?id=111555
This bug degrades the experience to the point where the computer is
not usable for every-day work, although it functions enough to do
debugging.
Restarting the computer with one of the displays unplugged makes the
initial symptoms go away, and the system seems usable, although I am
still getting some strange lockup issues with the display at shutdown.
The terminal reports stack traces with amdgpu calls. (I may file a
separate bug for that issue.)
