Dell Latitude D810

[Eric Anderson]

Running FreeBSD-6-STABLE, I'm able to suspend successfully, but resuming 
makes the machine boot up as if it was powered off.  Any hints on what 
to start looking at?

I've including the console output of the various renditions I've tried, 
in case it helps.

Also, more details can be found here:

Thanks!

with apic disabled (but compiled into the kernel), suspend immediately reboots just after suspending:

with apic not-disabled, and compiled into the kernel, 
successfully sleeps, but resuming just boots the machine.
