[Bug 183461] Re: ksoftirqd/1 using 50% CPU or above
Actually it only happens when using the live cd. I remember when I installed 9.10 happening the same. It only happens when I install kubuntu using the harddisk method described in https://help.ubuntu.com/community/Installation/FromLinux, and when the SATA cdrom unit is connected, although there's no cd/dvd on it. If I disconnect the CD/DVD unit, the ksoftirqd process comes to normal. Since it happens when booting from the live cd, I can't tryout with other kernel, since this would require installing or rebooting. Once kubuntu is installed, the problem disappears. -- ksoftirqd/1 using 50% CPU or above https://bugs.launchpad.net/bugs/183461 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Andreas, first of all I thank you for the advices and your time. 1st trial: Lucid live CD. After getting back from suspend mode the whole X locked up. So I changed to console which behaved very weird(It didn't accept commands at all). Hence I couldn't get useable information from logs. 2nd trial: I installed linux-image-2.6.33-020633rc8-generic_2.6.33-020633rc8_i386 kernel and tried the same steps with the result of huge cpu load. Ksoftirqd used up 100% of CPU time.

Can you please try the same thing in lucid? Use a livecd if you don't want to install development release. Alternatively you can try the latest mainline kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33-rc7/ Looks like a kernel issue, since the above commenters mention different modules as the source of the error.

Gareth: thank you very much for posting the nohz=off kernel boot option. It really worked for me - I was desperate with ksofirqd/1 taking up lots of resources and heating the CPU.

[Bug 183461] Re: ksoftirqd/1 using 50% CPU or above
Can those experiencing this issue try the following kernel boot option ( un-blacklist any previously blacklisted drivers): nohz=off This disables the 'tickless' aspect of the tickless kernel (enabled by default in Gutsy perhaps other releases). ksoftirqd appears to be getting bombarded by by requests (probably from not quite fully polished hardware drivers).
