            Bug ID: 97785
           Summary: WebKitGtk+ 2.13.91 hangs my Intel GPU
           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: agomez at igalia.com

GPU dump error at /sys/class/drm/card0/error

I'm using WebKitGtk+ with my own JHBuild setting:
https://github.com/tanty/jhbuild-epiphany/tree/master

Epiphany 3.20.3 and WebKit 2.13.91.

I'm running Epiphany with the dconf key:

"process-model" = "shared-secondary-process"

The compilation was done with CMake args:

'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_FLAGS_RELEASE="-O0 -g1
-DNDEBUG -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g1 -DNDEBUG
-DG_DISABLE_CAST_CHECKS"'

Just by opening the last closed session, the desktop gets stall, even when
there is, apparently, no high CPU usage.

I can see this in the logs:

$ less /var/log/kern.log
