Hi! Is it possible that this https://bugzilla.kernel.org/show_bug.cgi?id=42691 is caused by the intel graphix driver? This does not crash: 1. reboot 2. log in+out again and again But this does crash quite often (after step 3): 1. reboot 2. play SecondLife again and again 3. log out or resume from suspend Thx. Bye Arne
