Re: kslowd causing periodic system lag

I just installed Ubuntu 10.10 on a Gateway 4024 Laptop. lshw shows it has:

display: VGA compatible, product: 82582/855GM Integrated Graphics Device

With the fresh install of Ubuntu 10.10 I get kernel 2.6.35-22 This gives me the kslowd00x problem.

So I downloaded and tried a 2.6.34 and a 2.6.36 kernel.

Here is my comparison using top. I booted each kernel, opened a terminal window ran top and left it running for 15 minutes. Here are the loads:

2.6.35-22 - - - - uptime 15 min - load average 0.66 0.60 0.46

2.6.34-02063401 - uptime 15 min - load average 0.00 0.02 0.04

2.6.36-020636 - - uptime 15 min - load average 0.14 0.25 0.18

So I'm sticking with the "34" kernel.

Here is how I installed the kernels:
http://kernel.ubuntu.com/~kernel-ppa/mainline/
then I chose v2.6.34.1-maverick/

then download three kernel packages

linux-headers-2.6.34-02063401-generic_2.6.34-02063401_i386.deb

linux-headers-2.6.34-02063401_2.6.34-02063401_all.deb

linux-image-2.6.34-02063401-generic_2.6.34-02063401_i386.deb

to somewhere/ (somewhere where there are no other linux* files)

I followed
http://thanhsiang.org/faqing/node/129
Then open a terminal window

$ sudo su

# cd somewhere/

# dpkg -i linux-*

I'm still working on the hold part...

reboot

GRUB will list highest kernel first so arrow down to get to "34".

I get a side effect. Now when it boots it complains of a low memory error. It didn't before and doesn't with kernel 35.
