I've got the bug since Ubuntu 12.04 release canditate. I haven't got any such a problem with Ubuntu 12.04 beta or 11.10.
I upgraded now to 12.10. Same problem and I feel, it's getting worse.
Working with Ubtuntu2d desktop, no such problem occurs.

As I wrote, I use ubuntu 2d right now. No crash, but system halts for a second every now and then (every hour).
