Comment 19 for bug 1176647

I have also experienced this bug on 2 different machines running 13.04. The first is an eeepc with an Atom 1.66GHz N455 CPU, and the second is a macbook pro 8,1 with a Intel(R) Core(TM) i5-2415M CPU @ 2.30GHz.

The bug is most reproduceable when playing videos, but on rare occasions (3) it has occured while browsing the web.

It caused me to downgrade to 12.04 on the eeepc.

Same symptoms (video lockup, except cursor, unable to switch to VT) however in my experience, the soundtrack on video playback kept running. A hard reset was required to use the system.
