If the "processor.ignore_ppc=1" option fixes it, it does not seem to be a 
problem with ath5k, but with something deep in the kernel. I think you should 
post on the linux-kernel@xxxxxxxxxxxxxxx ML.

Just in case it is something wilt ath5k, also post on 
linux-wireless@xxxxxxxxxxxxxxx. The wireless developers will see it there.

I assume that the "previous" kernel was 3.2, but be specific.
