[iwlwifi] 99% cpu with ksoftirqd/0
Last modified: 2007-11-30 17:12:04 EST
Description of problem:
Fedora release 6.93 (Rawhide)
Issue is with the kernel versions above 2.6.21-1.3116.
ksoftirqd/0 will use 99% of system resources, i have gone through few posts and
found that it may be related with iwlwifi, I am using D620 dell laptop
0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network
Connection (rev 02)
Currently i am not using wifi, a normal cable is attached but still the cup
consumption is high. I tried to remove it module which took 100% of cpu and than
locked up the box.
I have gone through many posts regarding this. I know that there are some issue
with this card, which are fixed with 2.6.21-1.3167 but those are related with
connectivity and not the cpu consumption( average load increase due to this).
There are many newer kernel available i due to load issue i am not able to use
those. Currently using 2.6.21-1.3116.
Any plans on this ?
still a problem on the current kernels ?
Nop Dave, things are working fine now with the latest kernel ...
