I have no APM turned on, completely disabled as a matter of fact.

I'm not using modprobe, rather installing it manually.  I just turned on
debug=6; I'm getting some interesting results in my log:

eth0: transmit timed out, tx_status 00 status 8000.
  Flags; bust-master 1, full 1; dirty 0 current 16.
  Transmit list 4327aa10 vs. c327aa00.
  0: @c327aa00  length 8000002a status 8000002a
  1: @c327aa10  length 8000002a status 8000002a
  2: @c327aa20  length 8000002a status 8000002a
...

and so on, with the @ numbers increasing by 0x00000010 from 0 to 15
(@c327aaf0).
