Suspend to RAM issus on a Dell 700m

[Petros Kolyvas <pkolyvas-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Hi Folks,

I finally got the "mem" state to function on my laptop (a state which I 
use extensively in that "other" OS when I'm working.)

A few issues though... my cpu, upon return, powers up to full-speed 
making it impossible to truly conserve power, sort of defeating the 
whole process.

It seems a rogue process (one which I can't kill)... listed only as 'sh 
-i" is using ~99% of the available CPU cycles. I have no idea where it's 
coming from.

Additionally the system gets less and less responsive with each return 
from the "mem" state. Probably due to many of these rogue processes 
building up and bogging the system down.

Below is the script I used, which I found online and modified (very 
little) as needed. Any insight would be greatly appreciated. Oh, I'm 
using FC4 w/ 2.6.12 (unpatched.)

Thanks,
Pk
