Re: [ath9k-devel] Pending ath9k bugs June, 2009

Ok I have some debug information.  I have a machine set up as a
multimedia file server and as soon as I get 3 minutes into a video or
so, poof, the connection gets dropped. I stream over http but it happens
when I scp a file too.

I have a watchdog that checks the connection constantly and if pings
fail, it brings wlan0 down (rmmoding everything from ath9k to led_class)
and brings it back up again. It's a pain, but at least I can keep the
server up for weeks at a time that way.

With the attached log, the problems seems to start at 21:31:33 when I
get lots of problems I don't understand followed by lots of "receive
FIFO overrun interrupt" and then later more and more
"AR_INTR_SYNC_LOCAL_TIMEOUT". By 21:32:03, my watchdog has noticed no
pings are getting through and by 21:32:13 it has cycled the interface.
The log gets noticeably smaller then, as the http file transfer has
timed out.

the log is at
http://joseph.cheek.com/sites/default/files/ath9k.jun22.21.31+32.log_.bz2
and the hwinfo is at
http://joseph.cheek.com/sites/default/files/hwinfo.ath9k.  I have a blog
entry with a little more info at http://joseph.cheek.com/node/7.

Let me know if you need more info or want me to file a kernel.org bug. 
The kernel is today's wireless-testing git tree.

Thanks!
