cat /proc/interrupts

57 IR-PCI-MSI-edge      eth0

the driver works after a while, but then a single message

"Disabling IRQ #57"

is sent to the console and the machine dies, nothing else is written in
the logs and remote ikvm becames unresponsive so there is no way to
bring more debug info back.. kernel 3.5.3 works ok.

Anyone else seeing this ?
