Hi,
I got this. Maybe it's an ath5k bug, just in case you saw it already, don't you
know what could be wrong here?
rate_control_pid_rate_init: 0 2462

ieee80211_sta_join_ibss: 00000fff rates
It's
printk(KERN_DEBUG "PUJ: %u %u %.8llx\n", sband->band, sband->n_bitrates,
sta->supp_rates[sband->band]);
right before the WARN_ON. And this
printk(KERN_DEBUG "%s: %u %u\n", __func__, local->hw.conf.channel->band,
local->hw.conf.channel->center_freq);
in rate_control_pid_rate_init.
00000fff means which rates were set to
ifsta->supp_rates_bits[local->hw.conf.channel->band]
The problem here is that it is after receiving a frame which caused the warning.
Thanks.
