I've noticed that when I do a suspend to disk. The
machine suspends PCI devices once (I notice this
because the ipw2200 wireless card shows its
suspending, then it locks/parks the HD heads, but then
all PCI devices are woken up and resume. The HD
spins up and then dumps memory contents to swap
partition, then it suspends all devices again? :)
Is this the right behaviour?
Shawn.

It is like that by design. The devices are suspened before we create the
system image (so that they do not get in the way) and we should wake
up some of them afterwards so that we can write the image to the swap
partition. Currently, we wake up all devices, which is not very efficient,
but it is simple enough to allow us to hunt bugs more easily. Finally, the
system is just powered off.
Greets,
Rafael
