Seems to be the new PID rate control algorithm. I believe Stephano
(CC'd) was sending some patches for this. Please try changing in
config.mk

>From this value:

CONFIG_MAC80211_RC_DEFAULT=pid

To this:

CONFIG_MAC80211_RC_DEFAULT=simple

and let us know how that goes. Oh and linux-kernel is the wrong list
to use, please just use linux-wireless for future e-mails.
