I can confirm this hardlock, though I have not saved any logs of it occuring, 
I remember the mieqEnequeue thing only too well. I can run stable for days 
without it occuring, but if I open Firefox, it is virtually certain it will 
occur within 5 minutes. Occasionally K3B will also cause it when I drag files 
from the file window to the layout window.

The hardlock can be circumvented by the magic sysrq sequence:
ALT+PRTSCRN (Hold while pressing other keys) R E I S U B

You can memorize that as "busier" in reverse. Allow some time to pass before 
pressing each subsequent key.
