Hi Aaron,
Although I have not looked at Oops report in detail (Sabbath is now on, can't do work!) but I am well aware of two (or more) bugs in that area and one of them may well be the cause of your oops I assumed the X86_FEATURE flags semantics to be the same on 2.2 as in 2.4 but then discovered it is different, fix is trivia) -- I will send Alan all the fixes real soon now. Possibly on Monday/Tuesday during the so-called "holidays" (I don't recognize those pagan feasts either :)
Regards, Tigran
