I too have noticed that large ethernet transfers can lock up
ARMLinux (2.2.1 and previous ones). This can happen quicker
if disk I/O is active at the same time. But without too much
disk I/O active, it still happens. It can happen when you
use non-flow controlled "flooding" via UDP or ICMP against
ARMLinux ethernet device, but you can also cause it happen
with TCP programs (ttcp for example) under stress. I've seen
this happen with DEC21143 ethernet on a couple of different
SA110 based computers. The result is quite consistent failure.
Right now this is the only instability I see in the current
kernel release.
