I need to join the club, my machine starts doing interrupt storms after
an uptime of ${random} on the IRQ19 (atapci0) thingy. Next time I'll
boot the machine I'll try to make it a verbose boot.  It's a production
machine which cannot restart on demand ofcourse :)

Note: First the problems occured much more, this was because the usb
interfaces on the machine co-existed with the atapci0 interface,
after disabling usb on the system, it took a lot longer to trigger
the interrupt storm (50 days if I recall correctly).
