Pending ath9k bugs June, 2009

[Luis R. Rodriguez]

We're down to 2 kernel.org bug reports for ath9k:

http://bugzilla.kernel.org/show_bug.cgi?id=13581
"ath9k doesn't work with newer kernels"
This is a regression between 2.6.29 and 2.6.30, someone needs to look at this.

http://bugzilla.kernel.org/show_bug.cgi?id=13141
"AR5008/DWA-552 - Very slow"
Patches have been supplied, needs user feedback.

If you are aware of any other issues please do report.

I will attempt to repro my xmit hangs bugs on today's wireless testing. 
I haven't submitted a kernel.org bug on it, just mentioned it on the
ath9k list several times.  I can submit a kernel.org bug for it tho,
assuming it repros (I've had it ever since Christmas, but who knows?).

Oh no, thanks for the reminder, that is another outstanding issue. Can
you provide the pcap output.

Hm, some script may not be using /bin/bash appropriately, but you may
just want to rm -f /bin/sh && ln -s /bin/bash /bin/sh for now.

rm -f /bin/sh && ln -s /bin/bash /bin/sh
make
/bin/sh: line 0: test: -ge: unary operator expected
/bin/sh: line 0: test: -le: unary operator expected
make -C /lib/modules/2.6.30-rc8/build
M=/home/dimko/compat-wireless-2009-06-20 modules
make[1]: Entering directory `/usr/src/linux-2.6.30-rc8'
make[1]: *** No rule to make target `modules'.  Stop.
make[1]: Leaving directory `/usr/src/linux-2.6.30-rc8'
make: *** [modules] Error 2



Make still fails.

About pcap, you probably din't get my last email. I have included log
files of tcpdump...
 I have had no packets going through wireless at all, during n only test.

unfortunately i cant compile anything currently

solution with rm -f /bin/sh && ln -s /bin/bash /bin/sh didnt help

compat-wireless-2009-06-20 # make
/bin/sh: line 0: test: -ge: unary operator expected
/bin/sh: line 0: test: -le: unary operator expected
make -C /lib/modules/2.6.30-rc8/build
M=/home/dimko/compat-wireless-2009-06-20 modules
make[1]: Entering directory `/usr/src/linux-2.6.30-rc8'
make[1]: *** No rule to make target `modules'.  Stop.
make[1]: Leaving directory `/usr/src/linux-2.6.30-rc8'
make: *** [modules] Error 2

If you want i can of course can  resubmit  tcpdump test, but i cant
install no ath9k drivers, as such test is pointless, as i only have
built in drivers left...

Sorry for replying to private email.

just to clarify, by all i mean, i cant compile ath9k drivers.
i could compile kernel for example

Dmitri

[Joseph Cheek]

ok, today's git tip is significantly better!  I get failed pings about
once every hour, down from several times an hour with the last stable
wireless-testing I could boot.  I'll get a log with modprobe ath9k
debug=0xfffffffff and send the log again.

Thanks!

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

[Joseph Cheek]

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!

Joseph,

Not sure what exactly you are tring. However, if you happen to notice the XMIT
being stuck, then please try the patch titled "Fix TX hang issue with Atheros chipsets"
and "schedule aggregation regardless of queue depth" (sent to wireless-testing
mailing list and yet to be merged into tip)

Thanks
Senthil

not sure if this helps, compat-wireless-2009-06-20 compiled just fine in openwrt with 2.6.30 kernel.

i have an idea.
i can try older drivers, something that was working with me before
perhaps, if it ever was... and if it does somewhat work, well, it'll be
rather easy to trace where problem came from.
Only question is, where can i see archives? i don't feel like using
developers tools, i am not developer and probably not bright enough to
use them anyway...

BTW, if anyone from developers is based in Republic of Ireland - i could
perhaps travel to him/her with ap and wifi card :)

Hm, well, there are the compat-wireless tarballs:

http://www.orbit-lab.org/kernel/compat-wireless-2.6/

These would not require git, etc. And the nice thing is they have
John's wireless-testing tag from which the code was pulled from so if
you *do* find a working release then this issue should be bisectable,
but for that you will need git.

If you want to attend this week's Linux wireless summit in Berlin
there were will be plenty of folks there.
