Hi Same on my machine with same chip and same kernel. If I use the switch on the side of my laptop to turn off wlan, ksoftirqd eats up one core of my cpu til I switch it on again or rmmod the iwlagn module. But when I switch it on before the device loses connection and then off a second time, I now get a (the) second ksoftirqd process eating up the other core too. This only happens if a connection is established, though. I'm not sure if this problem existed in 2.6.26 but I doubt it. (Will check if I find the time). My dmesg shows me this: [48067.257539] iwlagn: Radio Frequency Kill Switch is On: [48067.257539] Kill switch must be turned off for wireless networking to work.

Just haven't found the time. Thanks Mirco P.S.: added some cc's for iwlwifi and rfkill.
