            Bug ID: 92997
           Summary: [drm:intel_pipe_config_compare [i915]] *ERROR*
                    mismatch in has_drrs (expected 1, found 0)
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: debian at onerussian.com

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.

I now don't remember if I ever caught a clear traceback during a crash, but I
believe that it was since the upgrade that I started getting the Subject
message in the dmesg, then leading to tracebacks warning on the slowpath, e.g.
from earlier today

Today I have upgraded to yet another fresh nightly (was running the one based
on 4.3.0-rc7 for a while with occasional stalls), with fix for the build from
http://marc.info/?l=linux-kernel&m=144686213802377&q=raw , and upon reboot
still got the same error and a traceback (boot continued seems to be normally):
