            Bug ID: 104446
           Summary: GGPU HANG: ecode 9:0:0x00000000, reason: No progress
                    on rcs0, bcs0, vcs0, vecs0, action: reset
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: rvprasad at ksu.edu
        QA Contact: intel-gfx-bugs at lists.freedesktop.org

I have PopOS (Ubuntu artful) installed with kernel 4.14.0-041400-generic
#201711122031 on a System76 laptop with Intel i915 integrated GPU (519b) and
NVidia 1070 (driver v387.26).  When I enable "MSHYBRID" option in BIOS, the
screen goes blank upon booting and stays so as the system completes booting to
become operational without the display (I can ssh into the system).  When I
enable "DISCRETE" option in BIOS, system boots up with display using the NVIDIA
card but Intel GPU is not visible in tools such as lspci.

Observable behavior is the same 
 - with stock 4.13.0 kernel in PopOS
 - upon installing intel-microcode_3.20171117.1_amd64.deb

dmesg snippet:

[drm] GPU HANG: ecode 9:0:0x00000000, reason: No progress on rcs0, bcs0, vcs0,
vecs0, action: reset
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including
userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.

Since the display was off, I had to reboot the laptop and I could not find
/sys/class/drm/card0/error file.
