Well, as a starter, if you can reproduce it on a system (I cannot), 
then try to stick a few printks in there to print out the affinity 
mask as it gets changed plus dump_stack(), and see who changes it 
back?

Chances are it's irqbalanced? If not then the stack dump will tell. It 
shouldn't be too chatty.

(trace_printk() if you prefer traces.)

Thanks,
