Intel GPU crash corrupts fonts

[amay82]

The bug occurs regularly, without any special action. I'm just working in gnome-terminal und using Firefox.

Symptoms:
* While working, the system suddenly freezes for a few seconds (like a typical crash in the X system)
* Then I can continue work, but with corrupted fonts and views
* New windows are sometimes readable again

Don't know if the package is correct. Dmesg shows:

[ 3647.214489] [drm] stuck on render ring
[ 3647.214499] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 3647.214500] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 3647.214501] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 3647.214502] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 3647.214502] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

It is vital to attach /sys/class/drm/card0/error

[Yann Hamon (yannh)]

Just had the same error. Here is the requested file.

[Launchpad Janitor (janitor)]

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

[Nevidljivi Prijatelj (trulexkrpa)]

Same problem here, ehile working, usualy in web browser, system freezes for couple of seconds, and after it unfreezes fonts are corrupt and most letters are replaced by some sort of symbols. It can be fixed by rebooting the system. Error occurs on a daily basis.

I use a Haswell Pentium G3420 and integratet graphics card.

amay82, as per http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t430s an update to your computer's buggy and outdated BIOS is available (2.63). 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 provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status New. Otherwise, please mark this as Invalid.

Thank you for your understanding.
