This is not a really helpful answer since I didn't look to find the root
cause, but here's how the warning is decoded:
ath5k_tasklet_rx is called to process received packets, then it calls
__ieee80211_rx to deal with it. This in turn tripped the warning in
mac80211/rx.c:
if (!sband ||
status->rate_idx < 0 ||
status->rate_idx >= sband->n_bitrates) {
WARN_ON(1);
return;
}
Possible the rate index table hasn't been setup for the operating band?
