Subject: Asus P1-AH2 won't suspend (regression)

Hi,

I'm unable to get an asus P1-AH2 system to suspend (to ram). The issue
occurs at suspend time: the system displays "Suspending console(s)" but
does not turn off the screen and system fans.

I used to have suspend/resume working fine on this system using a
2.6.20.x kernel. Yes, I know this is a huge range... suspend has
been broken on this sytem since at least 2.6.22.x

I tried running 2.6.24-rc6 with verbose PM debugging and suspend/resume
event tracing. Still no luck, the last message I see is still
"Suspending console(s)". The information from event tracing seems to be:
  Magic number: 8:471:282
  hash matches device tty19

I'm not sure if that's any help. Is there any way to help figure out the
problem besides a git bisect ? would extra event traces during/after the
suspend console stage help ???

This is with an x86_64 kernel. .config file can be found at
http://lespinasse.org/config-2.6.24-rc6 if that's any help.

Thanks,
