Suspend to RAM issus on a Dell 700m

Suspend to RAM issus on a Dell 700m

[Petros Kolyvas]

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

Hi

I have mine working perfectly, you may check my site, and compare a few
things.

Re: Suspend to RAM issus on a Dell 700m

[Petros Kolyvas]

Your script works just as well (if not better), but that persistent
interactive shell using 99% of my available CPU continues to crop up.
I'm not sure where to go from here.

Thanks for the reply though!

And you cannot kill that thing? Like "ps ax" will give you the ID
number, and then "kill -9 xxxx" (xxxx is ID number) ?

If yes, you may put that in the waking part of the script, and it will
kill the bastard. If that isnt the case, I wouldnt know what to do. I
have 2.6.9 kernel, and that might be the case. 2.6.9 works like a charm.
Also try to kill as many running apps as you can prior to suspend, just
to test, and then resume, and see if it works. ALso try to suspend from
console (no X session, session manager running). If it works, you can
enable processes one by one, and see which one causes the system to
freak, and eliminate the process. 

I see you use cpuspeed. How about stopping that before suspend? Just a
blind guess though. This is what I would try if it was mine. Also just a
sidenote, powernowd is a superb CPU speed scaling (on demand) app. You
may check that out. All info should be on my site.

If you have anything you may add to the site, let me know, and I will
post it there.

Re: Suspend to RAM issus on a Dell 700m

[Petros Kolyvas]

I got your script working finally... turns out the problem was my fault
for not setting your lid script as executable and leaving the other
script still in place. Your script actually ran perfectly with no
problems and I have been testing it heavily (many suspends) since
without issue.

Thanks for the help and encouragement.
