[Bug 48395] Re: ipw3945 produces 99% cpu, making my laptop unusable

[SpEnTBoY]

I'm running into the exact same issue. I've checked some other forums
regarding the driver and it seems like there are quite a few people
experiencing this issue. Has anyone here heard of any fixes yet? I'm
kind of trolling everywhere hoping that there's some magic somewhere ;-)
I need this wireless working mostly as a matter of convenience for work
:-/

Some of my ouput:

The WiFi light goes crazy for a while while these plaster my logs and
dmesg then it all seems to settle and work for a bit. I've tried
generating tons of traffic, starting multiple sessions accross different
networks, leaving it alone ... nothing seems to really kick off this
activity it just *happens* randomly
