Processor usage at an almost constant 30%


Hello,

I haven't used slack for a long time, so I was waiting for 11.0 to be released to be a slacker once again...

During the installation everything went perfect, I used kernel 2.6.18.

After everything was done I decided to run gkrellm, I've always liked the little bugger... as soon as I started it it showed my processor usage to be ~30%, it's the first Slackware installation that I have performed where I have encountered this.

I don't know if that would be normal or not, like I said I've been away for a long time, if it's not, any ideas as to why that might be happening?

This is what I get when running top.


Thanks for any suggestions or light shed into the matter.

It's definitely not normal. Mine runs an average of 1-2% on idle.

But why udev is using that much processor time, I don't know. Perhaps its not detecting some hardware?

Does it continue to have 30% usage even 10 minutes later?

Edit: I guess I didn't have to really ask that. Your top shows that udev has eaten up 10% average (26 minutes / 4 hours (240 minutes) ) since you turned it on. does your ./dmesg or /var/log/messages reveal anything?

Thanks for your answer.

With dmesg I get...

Intel ISA PCIC probe: not found.
Intel ISA PCIC probe: not found.
Intel ISA PCIC probe: not found.
Intel ISA PCIC probe: not found.
Intel ISA PCIC probe: not found.


Over, and over... I guess that means (as you said) it's probing for something and not finding it... the problem is I don't know what to do with that information, hehe...

I guess my first step would be to figure out what the isa pcic probe is. Does it actually exist on your hardware? Is udev supposed to find it? Why is it looking for it in the first place?

Do you use PCMCIA? Memory cards?

PCIC stands for PC-Card Interrupt Controller.

I thought of something else. Is
/etc/rc.d/rc.pcmcia
executable?

If it is executable, and you do not use card services, It might be searching for something that you do not have. Make it non-executable and restart. See if it makes a difference.

Edit: I just looked, and in face rc.pcmcia has the PCIC Probe right in it! This might be our lucky break.

Edit #2: If you do use the card services, do you have the pcmcia-cs & the pcmciautils package installed?

Edit #3: Golly, I forgot what PCMCIA was until now. If you are using a laptop, you will need the pcmcia-utils packages (for the kernel 2.6). If you aren't using a laptop, you can just turn off the executable bit from /etc/rc.d/rc.pcmcia

Right on the money!!!

I use a desktop; I made rc.pcmcia non-executable, restarted, and 0% usage when idle.


Thank you very much.
