I'm not an expert here, but the debug message indicates that
ath5k_hw_reset failed with -EINVAL==-22. There are a couple of
possibilities where it failed exactly, you should uncomment the
following line in ath5k.h:
/* #define AR5K_DEBUG 1 */
If you still don't see more messages before the "unable to reset", you
can try merging the patch below(patch is against wireless-2.6 plus nicks
7/7 patchset + nicks remove fill_... patch). With that you should see an
error message and that will hopefully help the developers to help you.
