Suspend to disk.
I don't normally see interrupt 99 in use. Here's the current
/proc/interrupts, having not suspended:

I'm not at home at the moment, so I can't verify that it is irq 99 that
it says, but I'm pretty sure. I can check again this evening if you
like.
The messages are continually generated.

If you want me to try a patch when I get home, I'm more than willing.
Rebooting is slow! I want to be able to suspend again!
