I've also been hit by this bug, mentioned last month - but he guy had no
additional info. This is with compat-wireless 2009-10-09 and linux
2.6.31.3, all in master mode, using recent hostapd from git.
Might also be two bugs... first one being module warning and "ath5k
phy0: no further txbuf available, dropping packet" the other.

and then bit later:

and lot of these. Network traffic goes down. And even when it works,
network traffic is very slow (<50kB/s)
