I'm sorry. I was grumpy when I wrote this.

I have no useful information here since, as mentioned above, it's been
completely random thus far. It may also be something that was fixed in
my most recent update; time will tell.

This at least I can reproduce. It's only a problem when I'm first trying
to bring up the adhoc network. Once it's up, (i.e., another node as
associated with it) it stays up and is problem free.
dev.ath.0.debug: 0xc0080 => 0xc00e0<reset,mode,beacon,state,node>
I configure ath0 as follows:
ifconfig ath0 172.16.1.1 netmask 255.255.255.252 ssid x40 wepmode off \
mediaopt adhoc
And eventually I get stuck in this loop:
ath0: hardware error; resetting

ath_tx_stopdma: tx queue [1] 0, link 0

This is the device:

Anything else I can provide, please let me know.

Again, I apologize for the tone of my last email. I was just being
generally bitchy and it was certainly not directed at you.
