re: a panic at 0xf01b0384B
it's in nortqr..
This is excactly the problem  I see in 2.2 based machines.
we have MANY in the  field and occasioanally get hit by this.


someohow the vm system manages to confuse things
to the extent that the same process is on both the run queue
and a sleep queue.
I've been looking for this for more than a month and have not been able
to reproduce it, It just happens randomly out in the field.

I say the vm system, because there is always some connection
with the swapper process.
