BTW, in my Thinkpad x21e (Intel Wireless-N 1000) I've noticed a very
high (~80%+) CPU utilization by the "irq/42-iwlwifi" kernel process
with the 3.9.x series kernel (self-built from upstream GIT sources)
and 3.10. Not sure in what exact 3.9 version this behaviour
started. I'm using the standard 0.36+wheezy.1 (non-free) version of
firmware-iwlwifi.
