            Bug ID: 111919
           Summary: Intel card (Coffeelake) short freezes (hang) after
                    upgrade to kernel 5.3.4
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: not set
          Priority: not set
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: freedesktop.org at ochotnicky.com

                CC: intel-gfx-bugs at lists.freedesktop.org

I updated my kernel to 5.3.4 today and had a few short (few second long) UI
freezes. Freezes recovered and I found following in my dmesg:

[101184.000657] i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0
[101184.000659] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[101184.000659] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[101184.000660] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[101184.000660] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[101184.000660] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[101184.001664] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
[101394.022014] usb 1-11.3: reset high-speed USB device number 6 using xhci_hcd
[101752.002696] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0


I can provide list of more system components/libraries, but as far as I can
tell this is related to 5.3.4 kernel update. I've seen the freezes in a few
cases - mostly web browser usage it seems. I am attaching the card error output
from sysfs. If more info/testing etc is needed let me know.
