Hello,
I'm using Ubuntu Natty and the ath9k driver of the different kernel of
this distribution do not make my AR5008 pci express wifi card run well:
the connection is too slow or halted.
I tried to compile Compat-wireless but it does not compile:
#./scripts/driver-select ath9k

I tried different version of compat wireless and only the
compat-wireless-2011-02-13 compiles good on natty.
But it is not stable, I lost the connection several times per day.
In dmesg, I can see:

The connection is fast but the driver is totally unstable but it is the
only version I can compile.
Someone know why I can only compile this version? not the last?
Thanks for your help.

This looks like the same problem that cropped up on iwlwifi 32-bit
last week. That file is probably missing an include for linux/sched.h

Daniel, I followed your advice, I added:
#include <linux/sched.h>
in compat/compat-2.6.39.c
and ath9k compiles without problem.
Thank you very much.
