8086:0126 [ThinkPad X220 Tablet] Xorg freeze: drm:i915_hangcheck_hung

[Daniel Hahler]

I often see (short) GPU hangs lately, often when using the vertical scroll bar in Firefox.

It even happened that the whole system froze, but that did not happen recently.

From dmesg:

[ 1973.723500] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
[ 1973.723506] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
[ 1973.733691] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

Status changed to 'Confirmed' because the bug affects multiple users.

Probably a duplicate of bug 1140716 .

This still happens on Ubuntu 13.04 patched as of 7/26/2013 on a Lenovo T420.

kernel: 3.8.0-26-generic #38-Ubuntu SMP Mon Jun 17 21:43:33 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
lspci: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

Please prioritize as it's extremely frustrating. I can't seem to easily capture the error_state because it's cleared out upon reboot (unable to switch TTYs etc).

Daniel Hahler, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (1.39). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.
