Hello.
Is this the place to report net driver bugs?
Just tried to make a switch from 3.3.5 to 3.4.0 kernel and it seems
that something is wrong with RT2800USB driver. iwlwifi driver seems to
work pretty fine, so I assume that this is RT driver problem.
Here's some info:

Lemme know if I should add some /dev/random or anything else.
