Bug Description
I'm running maverick with kernel:
Linux earth 2.6.35-22-generic #34-Ubuntu SMP Sun Oct 10 09:26:05 UTC 2010 x86_64 GNU/Linux
I've just the browser opened, top says that my cpu is used a 1-3% and my system load is almost 9.60. There is a kslowd001 or kslowd002 or kslowd003 which appears in the top screen and it seems the issue which makes the system load so high.
The problem is already known and has been reported in many other bug reports such as: https:/
The solution is to switch to a 2.6.36 release where this issue has been resolved. Please provide a 2.6.36 with the ubuntu patches to fix the problem.
Thanks

I have the same issue with a Dell Inspiron 1150 (Intel 852/855 gfx) running ubuntu 10.10 on 35-22 kernel. I can't get the commit fbf81762e385d patch to apply, I always get hunk failed errors.
I tried the option "sudo -i && echo N >/sys/module/ drm_kms_ helper/ parameters/ poll" but there is no parameters folder and creating the local.conf with the options caused ubuntu to give an error at boot saying option 'poll' not found.
Can anyone tell me what exactly I'm doing wrong? Using kernel rc5 fixes it for me but my wifi doesn't work so I need to get this patch working somehow under kernel 35-22.
