Re-opening since it's affecting our 64bit 16-core FC12 system.

This is the error message I saw in our log today:

do_IRQ: 6.233 No irq handler for vector (irq -1)

And the same bug has been cropping up in the latest versions of Ubuntu as well:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/480997

So I'm wondering whatever happened to porting that patch over. Did anyone get
around to it?

And no, I don't have a reliable way of reproducing the bug. It seems to have
happened while I was untarring about three million tiny files onto a hardware
RAID10 array while at the same time a software RAID10 array over SSD drives was
doing re-checking. Basically very high I/O load.
