dmesg with rx580 amdgpu.dc_log=1
So what was the repro rate for the issue? Can you try to reproduce on the latest rawhide 4.15.0-0.rc8.git0.1.fc28.x86_64 and/or collect dmesg with amdgpu.dc_log=1 for the bad case? Thank you.

Thank you. I can do that over the weekend. Did you have a chance to capture a repro dmesg with dc_log=1?

Nullptr deref after powercycling MST display
I'm also affected by this. Setup: GPUs: RX 580 (used), R9 Fury Screens: 3xU2415, connected via DP. 2 of them connected via MST, 1 HDMI to disabled screen, 1 HDMI to Oculus Rift VR Linux x7 5.0.7-arch1-1-ARCH #1 SMP PREEMPT Mon Apr 8 10:37:08 UTC 2019 x86_64 GNU/Linux Window manager: i3 4.16.1 Crashes when disabling + enabling the secondary screen on MST. Under some conditions the screen is not detected properly (instead of crashing the system) and powercycling the primary MST screen will crash the system. (Primary MST screen: The one plugged into the GPU, secondary: plugged into the primary screen) dmesg: https://bugs.freedesktop.org/attachment.cgi?id=144079&action=edit (with dc_log=1 but it seems like it was removed?) [ 27.292118] amdgpu: unknown parameter 'dc_log' ignored @51.6 I've disabled the secondary MST screen, the crash a couple of seconds later is when turning it back on. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
