--- Comment #3 from Vik-T viktor@troja.ch --- I hope it's ok if I bump this bug report. It's been almost a month since I reported it and I haven't received any feedback since.
Nothing really new I can report as such otherwise. The problem still exists, the driver crashes regularly. I noticed a certain possible correlation with usage: When I'm working on the computer, the problem may happen several times a day. When I'm not touching it, it may take up to 2-3 days for the driver to crash.
Sometimes logging on through ssh and restarting the desktop manager (lxdm) helps already. But most of the times, only a reboot solves the issue.
