error info from /sys/class/drm/card0/error

Hello, everybody. I was able to reliably reproduce this issue with the kernel in use above, 3.15.10-201.fc20.x86_64.

Then, after the upgrade to kernel 3.16.2-200.fc20.x86_64, the error is less severe, at least for the one time I've tried it.  X and the Chrome web browser remain running, and the following messages appear in the dmesg output:

[  163.704211] [drm] stuck on render ring
[  163.705282] [drm] GPU HANG: ecode 0:0x9f47f9fd, in chrome [1613], reason: Ring hung, action: reset
[  163.705287] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[  163.705289] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[  163.705291] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[  163.705301] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[  163.705303] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[  163.707997] [drm:i915_reset] *ERROR* Failed to reset chip: -19
[  164.039708] chrome[1720]: segfault at 280 ip 00007f2440249c98 sp 00007fff7f66e540 error 4 in i965_dri.so[7f243ff1d000+500000]

I'll attach the data that I copied out of /sys/class/drm/card0/error.

Let me know if I can provide more information.
