Why does a single spurious interrupt cause it to be shut down? I can
It doesn't.

see if the interrupt is stuck on and keeps interrupting constantly, but if it's just the occasional spurious interrupt, why not just ignore it and move on?
The interrupt is usually level triggered so it continues to create
interrupts until you silence it. The thresholds are about 10,000
interrupt events and on newer kernels we also reset the count if we don't
see any for a while. That works for most stuff except the thinkpad
bluetooth problem.

Which is confirmed hw problem now, btw.

What problem is that, exactly?

My Dell has an internal USB BT adapter that briefly appears
and then disappears again on resume (or stays if I have "enabled" it
via the BIOS key).

I wonder if that has anything to do with the (new in) 2.6.23 pauses
that machine has on resume (about every 10th time).
