When running on the console the command 'pm-suspend', I get the following:
$ pm-suspend Error: kernel cannot suspend to ram. $
I just looked at pm-suspend's source. This error message means that in /sys/power/state there's no mem present (try 'cat /sys/power/state' to see what is supported).
$ cat /sys/power/state standby disk $
The kernel thinks this machine can not suspend to ram.

This one can cause problems at resume, but not at suspend time :-) ...

Is this a desktop (Pentium M was for mobile AFAIK), isn't it?
Yes, my computer is a desktop one.
Has this machine ever been able to suspend to RAM?
Never.
If so, have you changed something in your BIOS?
Please check what these two say: grep -i 'power states' /var/log/messages grep -i 'suspend' /var/log/messages
Both commands return nothing.
Thanks, Doncho.

I've seen something like / long ago :-) /: 'Software Suspend has malfunctioning SMP support. Disabled :(' but have no idea what the current status is...
