Bug ID: 111139
Summary: linux 5.2: rare NULL pointer dereference when SteamVR
idles
Product: DRI
Version: DRI git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: haagch@frickel.club

dmesg with null pointer dereference
Vega 64, mesa git b68778e6de2, Linux 5.2.
I am relatively sure this started happening with linux 5.2 and that this did
not happen on 5.1.
When SteamVR is idle for a while (i.e. the VR headset is not moved), it stops
rendering to not waste resources.
When it does this, there is a chance that a kernel bug happens, see attached
dmesg.
It does not happen very often, but often enough that I'm relatively sure it
started happening with 5.2.

I'm being told that this bug does not only happen with SteamVR, and that it has
been triggered without SteamVR running, possibly by Chrome/Chromium.
