            Bug ID: 87176
           Summary: Haswell: stuck on render ring
           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: n.schnelle at gmail.com
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
                CC: intel-gfx-bugs at lists.freedesktop.org

I have built new desktop pc with haswell pentium g3420 and integrated graphics.

I get often gpu hangs while web browsing with firefox.

dmesg:
 [drm] stuck on render ring
 [drm] GPU HANG: ecode 0:0x87d3bffa, in kwin [1636], reason: Ring hung, 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.
 [drm] GPU crash dump saved to /sys/class/drm/card0/error

This happens on Kubuntu 14.04 with kernel 3.18 (3.17 effected too) and latest
drivers from intel graphics installer.
