kernel 2.6.2 and apm suspend

[paleo]

Hi,

 

I'm running mdk9.1 (with a lot of customization) on a Toshiba Satelite 1805 and I just installed kernel2.6.2 from kernel.org. After a bit of messing around, I got it running pertty well (some modules names changed from 2.4. series so I had to take care of that mostly and some modules I have to load manually somehow - I do it in rc.local).

 

But I have a few problems with apm suspend (swsups doesn't work for me - never did; it always hangs when bringing up USB).

 

1. when I choose to restart network during suspend (in /etc/sysconfig/suspend), the process hangs. It cannot unload the eepro100 driver for my ethernet card (when this happens, I can't unload it manually either and I have to do a forced shutdown with alt-sysrq-S,U,B ). This is kind of random; sometimes the unloading works, at other times it will hang. I can get around this one by choosing not to restart the network but why can't I unload the module in the first place? Never had this with 2.4.22.

 

2. my ps/2 mouse goes nuts after resuming - the mouse pointer behaves as if it were getting fed by a random number generator. I can prevent this from happening by unloading the module psmouse before suspending. But then I have to load it again. This never happened with 2.4.22 either.

 

With regard to 2, I figured out how to unload the module automatically. I just inserted the line

rmmod psmouse

in one of the suspend scripts. But I can't get it to load automatically. I thought it should do it when I insert modprobe psmouse somewhere but it doesn't. Here is a modified script:

 

#!/bin/bash
. /etc/sysconfig/suspend
ARG=$1

function suspend {
   if [[ $RESTART_NETWORK == "yes" ]];then
 rmmod psmouse
   fi
}

function resume {
   if [[ $RESTART_NETWORK == "yes" ]];then
/sbin/modprobe psmouse
   fi
}

case $ARG in
   suspend)
suspend
;;
   resume)
resume
;;
esac

 

As you can tell, I cannibalized the /etc/sysconfig/suspend-scripts/suspend.d/network script since I don't use the network options anyway (restarting network is a bad idea on this laptop). The suspend part works, the resume part does not. Why? Any ideas? I kinda wonder if I'm misunderstanding the function of the resume part...

never mind the ps/2 mouse. It's working now for some reason. I hope this isn't random.
