Ok, I did that. Now I'm getting an error there's not enough swap space 
(logical enough I think).

/critical section: Counting pages to copy[nosave] (pages needed
:18062+152=18574 free 14689)
Couldn't get enough free pages, on 3885 pages short.
Kernel panic: Not enough free pages

If both swap partitions is disallowed, and one swap partition isn't enough 
space, is there anything I can do now to make this work? I'd really like to 
get suspend working.
I know at one point 128MB was the limit on a swap partition. Is this limit 
gone now?
How technically difficult is it to make swsusp work with multiple swap 
partitions?

Cheers,
Shaun

swsusp: Unable to find swap-space signature

[Shaun Jackman]

I think I'm making progress.
I have 128 MB RAM, and a single 256 MB swap partition.
I pressed SysRq-D, swsusp displayed all sorts of successful messages, and 
then rebooted my computer. (can I get it to poweroff my computer instead of 
reboot it?)

When it started up again, the kernel displayed the message "Unable to find 
swap-space signature" and went on to fsck. The swap partition seemed dead. I 
ran mkswap and swapon to get my swap partition back.

Any idea what went wrong? I'd love to get swsusp working.

Thanks,
Shaun

This is not enough RAM, there's enough swap. You may try quitting some
applications.

Yep.

Should not be that hard. But you'd have to pass both partitions on
command line, etc.

Yep, you need to pass resume=/dev/hda3 to resume (on kernel command
line).
