I am not sure what's causing this. *Any* pointers would be helpful. I am no expert in wireless tech, but am tasked with implementing basic wifi feature-set for the product.
I suspect the ath_isr is not returning a good value to the kernel interrupt framework, but it might be a backports/compat issue.
