Subject: swsusp for ppc440

Today I worked for enabling swsusp for ppc440, again
on kernel 2.6.12.
I wrote some changes for arch/ppc/kernel/swsusp.S, however 
kernel was stopped, before hibernation is taken place with
following messages.

	# echo disk > state
	PM: prepare: Attempting to freeze processes.
	Stopping tasks: ===|
	Freeing memory... done (0 pages freed)
	PM: prepare: OK.
	ide-disk 0.0: suspending
	serial8250 serial8250: suspending
	
	 .. nothing happen
	
It seems to be stopped at console device.
Do anyone point out where and how to exclude system devices
like console and swap from device suspend procedure as 
preparation of swsusp?

Thanks,
