Subjectnobody cared about IRQ 19 (firewire, on a HP 2510p notebook)
I just got the following in dmesg a few minutes after booting my
notebook which was idle at the time this occurred. This was with
2.6.25-rc6 but I've seen the same with 2.6.22 (see the attached
dmesg from 2.6.22).

irq 19: nobody cared (try booting with the "irqpoll" option)
Pid: 0, comm: swapper Not tainted 2.6.25-rc6-amd64 #1
