Arh **** it's back... but I guess I do know why!
Heads up! 0.9.4 needs definitely a new HAL,
the current one has a few bugs in "Master" and "Station" mode:
- no beacons xmits on AR5008.
- If countrycode is NOT 0, the module won't load!
(Afaik there's already a ticket for this)
- where are the 3 antenna profiles for diversity/MIMO?
- "management frames" Denial of Service (DOS)
- If the rx-queue gets full, because of a Intel 4965N WIFI Card
that spits "associations requests" like a machine gun
(or a packetspammer and injection)
=> "rx FIFO overrun"
- If the tx-queue fills up: (because hostapd/wpa_supplicant
is very eager to send disassoc/deauth for every associations
response)
=> you'll see a few "ath_mgtstart: Dropping; no available
transmit buffers." lines before the kernel panics in
ath_hardstart.
Is there any hope? Or has Atheros dropped it's linux support thanks to the
openhal & ath5k people?
