troubleshooting Atheros 9280

[Waitman Gobble]

Hi,


I have an Atheros 9280 that 'connects sometimes', could be a bad card. (?)

here's syslog entries:

ath0: <Atheros 9280> mem 0xf01000000-0xf010fff irq 19 at device 0.0 on pic7
ath0: [HT] enabling HT modes
ath0: [HT] 2 RS streams: 2 TX streams
ath0: AR9280 mac 128.2 RF5133 phy 13.0
ath0: 2GHz radio: 0x00; 5GHz radio: 0x00c0
ath0: ath_reset_grablock: didn't finish after 10 iterations
ath0: ath_reset_grablock: warning, recursive reset path!
ath0: ath_chan_set: concurrent reset! Danger!
ath0: ath_start: sc_inreset_cnt > 0; bailing



I have not yet been able to get this card connected to 5GHz/HT40. but "usually" 11g works. Today it's being super-stubborn. :)

I noticed if i do ifconfig the channel "floats" all over the woodshed. in 11g mode it's bumping around from 2 to 12, 11a mode from 2 to 169 (i think). Seems like it settles eventually and connects.

Any troubleshooting tips/help appreciated. 
Thanks,
