I imagine that these are the "9 commits" you mean:

Most of those look fairly harmless so long as you don't define
CONFIG_ATHEROS_AR231X.  Just to narrow things down...if you only revert
the first 8 (i.e. leave aeae4ac alone), do you still have problems?
Or does it still "stabilize"?

That patch converts the driver to the generic DMA API.  It seems
OK at first glance, but I suspect it is the only one likely to be
effecting your situation.
