hi,
after upgrading to 11.1, double faults appear in mass. Typical stack trace in vmcore:
Best provoked by activity under Xwindow (~10 mins of active browsing are enough), but can appear without starting X.
ZFS isn't in effect. Changing from intel video driver to vesa don't help. The stock generic kernel and custom kernel both show the same.
There were no such problems before system upgrade. Memtest doesn't expose any errors.
What else can be explored?
