Comment 272 for bug 141613

While listening music on Deezer, firefox becomes unstable after a lot of time (more than 30 minutes), it becomes slow, then the display freezes, my screen is full of white / grey. And after a few seconds, the PC reboots !

I'm using Ubuntu 10.04

Extract of my /var/log/messages :
