As the subject says, 2.6.28-rc7-wl git pulled Dec 6 exhibits a kernel
panic when doing "iwlist ath0 scan" as root under the ath9k driver.
Machine dead, panic LED blinking.

Scan as normal user is OK.

Ick! Panic as normal user as well when using the graphical "Wicd
Manager" to Refresh (ie scan). Possibly it does its thing as root?

First panic was as root on a fresh kernel without any graphics driver
(plain terminal). Second try was as a normal user in said plain
terminal - was OK. Logged out and in as root to scan -> panic.

Installed graphics driver and ran as normal user under X. Wicd handles
the wpa_supplicant etc. Scanning in an xterm as myself was OK. Later
tried the Wicd Manager Refresh thing out of curiosity. Panic.

It would be helpful if you could capture the oops messages using a
serial console, netconsole, or even with a digital camera.  You may
also want to open a bug at bugzilla.kernel.org.

Thanks!

I'm currently a bit miffed with the linux dev community since the
address I'm using won't get through spam filters at lkml (and a letter
to vger admins has had no effect), so not too keen on putting work
into debugging.

Wireless accepts my mail obviously but I still wanted to see if anyone
was interested (or a dev could trigger it) before rolling up the
sleeves.

My oops transcribing days are looong gone but I'll take a low res
picture and pastebin somewhere - or attach in a separate letter directly
to a dev.

[patch snipped]

It fixes the kernel panic with root "iwlist ath0 scan" but after that
the network dies without a sign of any kind (iwlist, ifconfig etc is
normal, nothing in logs). Tried several times. Boot -> ping local and
remote machine OK -> "iwlist ath0 scan" -> ping nonfunctional: 'no
route to host' or some such message.

Sending you a picture of the panic in a personal letter. Don't know if
it will do any good since only the last part is visible on screen.
Taken outside of X in plain terminal. Tried to snap from inside X in
both an xterm and a kterm but the panic message never reaches that
high in the chain. Instant death!

Ok, thanks for testing.

Can you check if this patch makes the connection stable ?
Please apply on top of the earlier patch.

Sorry to say, no change. After root scan telnet gives "no route to
host" and ping just reports 100% packet loss. But iwconfig keeps
updating its info regarding link quality and signal strength, like:
Link Quality=82/100  Signal level:-42 dBm

Which channel are you using ? And is it HT40 ?
Also please post the debug log, you can do 'insmod ath9k debug=0x00002000'
to get a fair amount of debug information.

Thanks.

I've seen you asking this from other users, and like them I don't know
about that HT-prefix. All i can give you is the configuration of my AP:

_D-Link DIR-655 Access Point_
Security Mode: WPA-Personal
WPA Mode: WPA2 Only
Cipher Type: AES
802.11 Mode : 802.11n only
Wireless Channel : 2.412 GHz - CH 1
Transmission Rate: Best (automatic)
Channel Width: Auto 20/40 MHz

So if it's the channel width you're asking about, then I have no user
control of the 40 MHz. I can only choose 20 MHz or this Auto 20/40 MHz.
The AP calls the shots here...

> Also please post the debug log, you can do 'insmod ath9k
> debug=0x00002000' to get a fair amount of debug information.

Yeah, if I had had CONFIG_ATH9K_DEBUG=y set, yes ;-) OK, ran a new
kernel (using the two patches you posted) and /etc/modprobe.d/options
containing "options ath9k debug=0x00002000". Didn't have the patience
to brush up on manual wifi juggling with all the ifconfig, route,
iwconfig, wpa_supplicant, dhclient options. Just using the system as it
was during the prior runs.

Here's the full log since I have no idea what can be considered
important. Machine is a notebook AMD Athlon(tm) 64 Processor 3400+ with
2 gig memory.

Booted machine at 13:24:23. Pinged local and external machines around
13:25:10. Another ping session at 13:29:00 just to make sure the net
still was ok. "iwlist ath0 scan" around 13:31:00. Tried ping
unsuccessfully after that. Waited another five minutes, but nothing
else showed up in the logs.

Right, and from the log below, it does choose HT40.

This shouldn't matter since ath9k doesn't use minstrel.

Yep, ping won't work after that. :)

This indicates that HT40 has been chosen.

The problem is this:

After association, ath9k has to set the appropriate channel width on doing
a scan and mac80211 comes back to the home channel. Currently there is no
such means to do that, and this why pinging fails.

We'll work on a solution, but until then you would have to choose HT20 in your AP.

All protocols are affected ping, whatever lies below telnet and http
through lynx was dead as well.

Ok, I'll try this version out a bit first with heavy p2p-transfers. If
it survives I might stick with it (2.6.28-rc6-wl died after awhile)
otherwise I'll go back to my all time favourite 2.6.27-rc5.

Wicd manager seems to keep a static list of APs in the environment I've
already scanned, so the issue is normally of no concern.
