[ath9k-devel] openwrt - ath9k does not load: probe of ath9k failed with error -22

[Florian Reitmeir]

Hi,

i do own 2 linksys wrt160nl, which use ath9k.

i flashed both in the last weeks several times, and ath9k was loading
nice. since yesterday, one of them can't load ath9k anymore. reflashing
with the original firmware of linksys didn't help.

here the kernel dmesg:

ath9k ath9k: failed to initialize device
ath9k: probe of ath9k failed with error -22

i use openwrt trunk, with compat wireless from 3.11.2009. is the device
broken? if not how to tell, how do debug?

thanks

On what kernel? We've seen one case now where on a specific x86 platform
some new changes instroduced on 2.6.32 rounded up the PCI memory area
incorrectly and had an impact on devices like sky and ath9k. For more
information please see:

http://bugzilla.kernel.org/show_bug.cgi?id=14402

There is a fix for this now available and in Linus' tree.

But -- wrt160nl doesn't run x86 :) I take it, so... lets see.

You want to enable debugging as I explained to the user on the bug
report above. In the bug report you can find the same exact situation
and how I explain to get more information to further debug this issue.

Please post your dmesg logs once you get debugging enabled, and enable
it completely and load.

Compat-wireless could use a fix for ./scripts/driver-select ath9k to
enable ath9k debugging, but I haven't gotten around to it yet so for
now please just compile all the drivers.
