Description Adam Williamson 2018-06-20 15:51:50 UTC
Yesterday I bought a Radeon RX550 adapter (PCI ID 1002:699f) to replace a dying GeForce for my desktop. It worked OK all day, but when I tried to suspend the system at the end of the day, it failed - the system was left running but unresponsive and had to be reset.

Looking at the logs of the boot which ended with the failed suspend attempt, I see this:

Jun 19 23:00:07 adam.happyassassin.net kernel: kernel BUG at drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:4708!

...and that's all - the trace I'd expect to follow the 'kernel BUG' line does not appear.

This is on Fedora Rawhide with kernel 4.17.0-0.rc7.git2.2.fc29.x86_64 . The desktop is GNOME on Wayland, and I have two displays attached to the adapter, one via DVI and one via DisplayPort.

Just noticed that kernel is a few weeks old, will re-test with 4.17 final and 4.18 RC shortly.
Comment 2 Michel Dänzer 2018-06-20 16:30:01 UTC
Should be fixed by commit bc13f2f88eae63af943ab967cb14bb602f8f2eeb "drm/amd/display: Update color props when modeset is required".
Comment 3 Adam Williamson 2018-06-21 16:29:06 UTC
Yup, confirmed, works fine with 4.18.0-0.rc1.git0.1.fc29. Thanks.
