DragonFlyBSD

Here is a coredump:

If you can reproduce the problem you might test whether the wlan_serialize branch from
git://leaf.dragonflybsd.org/~hofmann/dragonfly.git fixes the issue.

hmm... Why not to merge it in the "master" branch?

I don't have commit rights. If you could test it successfully it might increase the chance that it get's committed eventually.

1. Very good news: I haven't panic any more. Continue tests...
2. Don't know is it bad news, or may be ignored: in the /var/log/messages I see
Mar 8 10:03:50 led kernel: ath0: hardware error; resetting

10 hours works well. But I have tons of "hardware error; resetting" in the syslog. And some "ath: ran out of descriptors":
Mar 8 19:30:44 led kernel: ath: ran out of descriptors
Mar 8 19:30:45 led last message repeated 34 times
Mar 8 19:30:53 led kernel: ath: ran out of descriptors
Mar 8 19:30:53 led last message repeated 15 times

Now I have these messages in syslog:
ath0: bad series0 hwrate 0x80, tries 1 ts_status 0x0

and network does not work. /etc/rc.d/netif restart - restores network.
