It fails during boot or shortly after that when clicking in gnome2
desktop. I had BFQ as a default scheduler.

Now I set CFQ as a default and it boots (as expected).

root@duo:~# cat /sys/block/sda/queue/scheduler
noop deadline [cfq] bfq
root@duo:~# echo bfq > /sys/block/sda/queue/scheduler
root@duo:~# dmesg | grep WARN
WARNING: CPU: 1 PID: 1 at net/wireless/reg.c:479
regulatory_init+0x88/0xf5()
root@duo:~#

Hmm, and I seem to have pretty much functional system.

I'll try to do some benchmarks now.
