Since the iwi driver doesn't want to join the wireless network at work (I opened up a \
pr for it), I decided to try the ath driver instead.   The card is an Atheros 5212.

Unfortunately, I'm having even more serious problems with this card:

ath0: ath_chan_set: unable to reset channel 7 (2442 Mhz, flags 0x480 hal flags 0xc0), \
                hal status 3302560252
ath0: ath_chan_set: unable to reset channel 52 (5260 Mhz, flags 0x140 hal flags \
                0x140), hal status 3296823488
ath0: ath_chan_set: unable to reset channel 56 (5280 Mhz, flags 0x140 hal flags \
                0x140), hal status 0
ath0: ath_chan_set: unable to reset channel 60 (5300 Mhz, flags 0x140 hal flags \
0x140), hal status 3304978572

It cycles through various channels till:

ath0: device timeout
ath0: ath_reset: unable to reset hardware; hal status 3232887468

And then it starts with the "unable to reset channel" errors again.  This continues \
till I run '/etc/rc.d/netif stop ath0'

When I go to remove the card, the kernel panics:

cpuid = 0
KDB: enter: panic

Just as with the iwi driver, this is on 7.1-STABLE...  Built today (with DDB and KDB) \
but originally pulled from cvsup on January 15th.
