The problem only occurs after some time. In the case shown in the log the system ran fine for 15 minutes and then triggered the oops.
In another case I was running VirtualBox. It ran fine for some time but the system hung when I tried to close the guest system.

Yes. Seen no problems since booting with 'nopat' and done a successful suspend/resume. With 'pat' I saw the problem 3 times after a short period of use.
