On my HP 2510p I get the following in dmesg during near the end of most
resumes from suspend to RAM:

Disabling IRQ #19

There also seems to be an interrupt storm during suspend/resume when this
happens:
 19:      99968         33   IO-APIC-fasteoi   ohci1394

This patch gets rid of both issues and makes the resume as a whole
significantly faster.

As was pointed out in http://lkml.org/lkml/2008/12/6/127, this does not
fix the cause of the interrupt storm.  However, since the source of the
interrupts could not be determined yet, we make the system at least more
usable with this change.
