I run it in 11a mode exclusively. It has recently become very unstable, exhibiting hard lockups nearly constantly. I tried to go back to -current as of around Christmas but the lockups didn't (seem to) go away. I've been incredibly swamped lately, wrapping up a former project and beginning a new job, so I haven't had the time to spend on this until now. Today I began to diagnose the problem. It is indeed a hard hang; the (firewire) console is unresponsive as is the GDB link. It seems to happen while I'm in X (using nvidia-driver from ports, which had a bug I just fixed) although it has happened at least once while I was using the regular non-X console. There is nothing obvious going on when it happens, I'm just using the system and it locks tight. Before I begin to suspect hardware I want to try to eliminate the software element. I've placed relevant information at http://www.exit.com/Archives/FreeBSD/hang-pr-info.txt This includes the dmesg (also appended below) as well as ath-related debug output from ./athdebug 0x800d8120 dev.ath.0.debug: 0x800d8120<reset,watchdog,beacon_proc,calibrate,state,node,fatal> ./80211debug 0x04000000 net.wlan.0.debug: 0x4000000<xrate> I don't think it's related to the recent cpufreq changes, since the hangs started before I picked them up and began running with them. This problem has rendered my laptop nearly useless. If anyone can suggest any way I might narrow this down a little further I would be very grateful.
