Bug ID: 107300
Summary: [REGRESSION] NULL pointer dereference when waking up
monitor
Product: DRI
Version: XOrg git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: mr.nuke.me@gmail.com

dmesg
I'm noticing this with linux-17.6 on an RX 480, but did not experience this
problem with linux-4.16 and earlier.
I let the machine without any input for a while, and it automatically puts the
monitor to sleep. To wake up the screen, I move the mouse or hit the keyboard.
About a third of the time, the login screen comes up, and there's no response.
SSH then dmesg points to an amazingly well crafted NULL pointer dereference in
[amdgpu].
Surprisingly, this isn't some 4billionk triple-gazillion monitor setup, which
I've always had driver issues with. This issue happens with a single display.
For fast access, this is the backtrace:

I was not able to observe any improvement with the patch in bug 107153
I should have mentioned that the monitor is connected via DP.
