I just experienced the funny slow down until kernel death experience again

The dmesg log is full of a long stream of the following

wait_on_irq, CPU 0:
irq:  -1 [0 0]
bh:   0 [0 0]

Argh !

The global irq count should never _ever_ get to -1, that's very bad...

Either some weird codepath I haven't manage to figure out, or,
and that's what I'm afraid of, for some reasons, atomic operations
between CPUs failed, which should obviously never happen !

Remind me which rev of the CPU it is ?
