I am trying to diagnose an issue with an Atheros 9462 card. The card is being
detected, and seemingly works (reports no errors with wpa_supplicant and
friends), however, the radios seem completely nonfunctional, as the card
doesn't actually transmit or receive anything (I checked by turning on packet
logging and running scans/wpa_supplicant).
There are errors reported in pciconf (it claims they are correctable errors):
receiver error, bad tlp, bad dllp. The Bluetooth subsystem also suffered
timeouts (very likely related).
I have confirmed this is not a hardware problem by booting into Linux with a
live memstick and running a scan.
I'm looking for advise on likely root causes and how to go about diagnosing the
problem (I've never diagnosed a problem on a *supported* card in FreeBSD
before, so I'm relatively unfamiliar with the process).
