AR9280 "bb hang" and other

Hi

I recently managed to hack my HP/Compaq BIOS to bypass the RF
Whitelist and replace the (crappy) bwn interface with a (decent)
ath card.

There are a few things -

1. The card has AR5B93 printed on the label, but its detected as:

ath0 at pci0:1:0:0:        class=0x028000 card=0x663211ad chip=0x002a168c rev=0x01 hdr=0x00
    vendor     = 'Atheros Communications Inc.'
    device     = 'Atheros AR5B91 Wireless Network Adapter (0001)'
    class      = network

ath0: <Atheros 9280> mem 0xfeaf0000-0xfeafffff irq 16 at device 0.0 on pci1
ath0: [MPSAFE]
ath0: [ITHREAD]
ath0: AR9280 mac 128.2 RF5133 phy 13.0

Everything I've read suggests it's actually an Atheros 9281.  It's
possible that the label is wrong.  I'm reluctant to desolder the
RF shield on the spare card I ordered to see what's actually printed
on the chip.




2. I'm getting these messages fairly often.  Transmission stops
briefly around these times:
