Subject: [ath9k-devel] Seem to have fried my AR9300 NIC?

Came back after a 1 week vacation and found the 3.3.8+ kernel spitting
timeout errors, and network devices will not 'ifconfig foo up'.

I rebooted into 3.5.0+, and see the same (or at least similar errors):

ath: wiphy0: timeout (100000 us) on reg 0xa2c4: 0x00158dd9 & 0x00000001 != 0x00000000

ath: wiphy0: Unable to reset hardware; reset status -5 (freq 2412 MHz)

This system ran stable for several months..so maybe the hardware just died.

But if anyone has any suggestions for debugging this more, please let me know.
