[Bug 558950] [NEW] [lucid] b43legacy PHY transmission error causes wireless networking to freeze or fail

[Scott Testerman]

Public bug reported:

Broadcom BCM4306 (rev 2) wifi using the b43legacy module periodically
freezes temporarily or even completely fails.  Checking dmesg shows
"b43legacy-phy0 ERROR: PHY transmission error" often dozens or hundreds
of times.

These failures don't seem to be caused by any particular activity, and
aren't even triggered by heavy network usage.  The errors can begin when
the network is almost idle or when it's under light or heavy usage.
Once the errors appear, wireless networking either freezes for a few
seconds to a few minutes, or alternately completely fails.
