Bug ID: 93017
Summary: complete system stalls while changing displays
resolutions on a hybrid (intel/radeon) system
Product: DRI
Version: DRI git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel at lists.freedesktop.org
Reporter: debian at onerussian.com
Originally reported within DRM/Intel
(https://bugs.freedesktop.org/show_bug.cgi?id=92997#c1) and was recommended to
seek support with Radeon peopl.
The story began a month or so ago whenever I upgraded my Debian testing/sid
installation with a new kernel (can dig out later if needed from which version)
to 4.3.0 : laptop started to freeze completely, usually when switching
displays (to/from external display)/resolution. My laptop is hp zbook 14" with
dual GPU:
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated
Graphics Controller (rev 0b)
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars
[Radeon HD 8730M]
which sits on the docking station (stalls happen without docking I believe)
which has a display connected via display port.
Running nightly of git://anongit.freedesktop.org/drm-intel from yesterday I
have managed to trigger the stall again: turned on 2nd display attached to the
docking station (also via displayport), which xrandr doesn't actually see as
connected, and usually it just shows the cloning of the 1st display (I guess
docking station does it internally). When I turned it off again, which lead X
to reset display and almost come back when it stalled... after reboot
journalctl -b -1 showed:

Not sure if this particular traceback is associated with all the stalls -- I
think that in majority of the cases system stalls before any log/journal gets
dumped to the drive so it is not usually accessible after reboot.
I also setup xrandr providers to enable external displays connected to the
docking station:
xrandr --setprovideroffloadsink radeon Intel
xrandr --setprovideroutputsource radeon Intel
but I think I had stalls prior doing that (but it was with older kernels etc)
