Synopsis: [panic] [ath driver] kernel panic: page fault with ath0 taskq

State-Changed-From-To: open->patched
State-Changed-By: adrian
State-Changed-When: Sun Feb 12 23:23:12 UTC 2012
State-Changed-Why: 
The patch in the PR should be fine - the RX antenna should be
validated before being used.

This should be backported to 9.x and 8.x. Although it _should_ only
be occuring when in 11n mode (since RX antenna may not be updated
for non-final RX aggregate frames) it may be occuring elsewhere.
