Hello all, I've a BCM4301 network controller (Asus L5800C laptop)
and trying to use b43legacy module to use it on a 3.2.0-4-rt-686-pae
linux kernel.
The controller works, but makes lots of noise in syslog.
Here's an excerpt:

What proprietary module have you loaded that set the "P" tainted flag?
Please repeat the WARNING without ever loading that module, and without the "P"
flag ever being set.
The WARNING is logged because interrupts are enabled at that point, and they
should be disabled.
