Thanks.  I assume you mean the brcms_c_wait_... warning when you refer
to an oops.  Separating the symptoms:

  brcms_c_wait_for_tx_completion warning: bug#672891
  connection resets, segfaults, general instability: bug#664767 (this bug)
  "AMPDU status: BA Timeout": bug#674430

I don't think his regulatory series[2] is likely to affect your
symptoms, but maybe it will be easier to get help once that has been
reviewed and applied upstream.

In the meantime, thanks for your updates --- this helps a lot.
