ksoftirqd/0 always using about 30%
Hi Gareth,
I m sorry for my last post I had not set the nohz=off parameter while booting
correctly,
This time however I set it permanently it by editing the
/boot/grub/menu.lst file and decided to observe for a couple of days
before giving my feed back, and based on my observation over the past
I tried booting with the nohz=off setting and this is what I observed,
Initially after logging in, the CPU usage was perfectly normal,
However after a couple of hours, the laptop went into power saving mode due to
inactivity and then when I resumed it,
ksoftirqd was back in action taking 80-90%
Sorry for the late reply ,
Well this is a result of the uname -a command :-
Linux stephen 2.6.22-14-generic #1 SMP Tue Feb 12 02:46:46 UTC 2008
x86_64 GNU/Linux
And attached is the file generated by the lspci command.
** Attachment added: Output of the lspci command on an HP Pavilion dv6000.
Can you try booting with the following kernel boot option:
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
I am currently on an HP Pavilion dv6000 (AMD Turion 64x2,1 GB RAM, Broadcom
Wireless) and have the same problem,
ksoftirqd is eating almost 50% of the CPU, sometimes it even hits 90-99% making
it almost unusable...

It happens on my laptop (IBM Thinkpad T43) too. Today I figured out,
that if I turn my wireless device on again (via Fn+F5) the cpu usage
drops down. After that I can turn if off without having the problems
again. Strange.

I see this effect when I turn my wireless radio off.
