ACPI resume doesn't work in i386 with SMP enabled on netbook

[Garrett Cooper]

Hi,
    /etc/rc.resume with GENERIC hangs on my netbook on resume (it
comes up with a blank black screen), so I removed all of the drivers
from my custom $KERNCONF (except the most essential pieces, i.e. acpi,
ata_cam, options INET, etc) and debugged the suspend/resume issue down
SMP support (it was hanging in the ioapic code). Once I disabled SMP
support, suspend/resume worked properly.
    My next question: how do I fix this issue or what should I do next
to debug it further :)?
Thanks!
