The points important for diagnostic are:
 - Do you see messages "can't fill rx buffer"?
   These messages mean that the driver experience allocation failures because
   of high load creating high memory pressure.
 - Do you see messages "card reports no RX buffers (no resources)"?
   These messages mean that the card realize receive buffer shortage, too.
 - When the driver manages to allocate buffers again, it issues message
   "restart the receiver after a possible hang". It should appear after the
   above messages.
The things may be complicated by the fact that the receiver hang may be
followed by an unreasonable transmitter hang.

A few months ago I performed stress tests and the driver worked well.
I'm going to repeat the tests this weekend.
