Created attachment 129691 [details] GPU crash dump separate bug based on comment of bug 71871 lspci: 00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 0b) Subsystem: Dell Device 05cb Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information: Len=0c <?> 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) (prog-if 00 [VGA controller]) Subsystem: Dell Device 05cb Flags: bus master, fast devsel, latency 0, IRQ 57 Memory at f7800000 (64-bit, non-prefetchable) [size=4M] Memory at e0000000 (64-bit, prefetchable) [size=256M] I/O ports at f000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 2 Capabilities: [a4] PCI Advanced Features Kernel driver in use: i915 Kernel modules: i915 this is in dmesg: [ 1.802111] [drm] Initialized drm 1.1.0 20060810 [ 2.010200] [drm] Memory usable by graphics device = 2048M [ 2.046585] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

Ah, scanline wait in the blitter gone wrong. Please upgrade to the latest released version of xfree86-video-intel and if the bug persists then please file a new bug report on bugs.freedesktop.org against xorg -> Driver/Intel again with the gpu hang error state attached. The kernel is just the messenger here, the bug is in the userspace driver. Hence closing this.
