Hi guys,

I have been receiving this error which appears to be the same error.

It causes the system to completely hang, video completely frozen.

The system log says it's related to Chromium, I had it happen to me twice
within a half hour. I wasn't doing anything too intensive, mostly had Chromium
open with Eclipse and Thunderbird.

First, some info about my system:
