After I do the printk testing to pinpoint the problem a little more

However, I didn't feel like iterating through the recompile

Is there any underlying reason for this question?

Another strange thing is: why doesn't the
tasklet finish, so that it
can be 'unscheduled'? I have my IRQ priorities higher than any other
RT threads, so I would expect that the tasklet can finish. Or is
tasklet_kill not-preemtible? that would be very strange as I would
expect that busy waiting on something in a non-preemptible code path
on a single-cpu system always deadlocks.
When are you going to report this to Ingo + LKML + the other -rt
developers?
