Ingo,
On an IBM Intellistation A-Pro I am seeing the bug regularly as seen below.
We also see this bug on an LS-20 blade. The way this bug is triggered is
to add 'irqpoll' to the kernel command line. If we remove this from the
command line, we don't see this bug. I know the easy answer is that if you
don't want to see the bug, don't use irqpoll. So we don't. But we thought
that just in case this bug does expose something real that it should be
reported.
That's a lock recursion caused by the irqpoll option. Needs some
thoughts to fix it. Thanks for reporting though.
