I have a 40GB ATV that I have installed Mythbuntu 8.04 onto the
internal disk. In general, the machine is working fine. Up until last
night, I was using only the wireless interface (eth1 in my case) and
it was ok, but I did have issues with insufficient bandwidth.

I ran a CAT5e cable to the machine, deactivated the wireless, and
enabled eth0. The wired interface comes up fine and gets an IP, etc.
Typical operations at the SSH console work fine. However, during
testing, I've observed some very odd behavior:

When I do something like this to send a big file from the ATV to
another machine:

appletv> scp bigfile.tgz remotebox:/tmp

...things go great. Fast speeds, etc. Unfortunately, when I try
sending a big file to the ATV, like this:

otherbox> scp bigfile.tgz appletv:/tmp

I get an initial burst of traffic through, and it just stalls, never
recovering. Seems like there is something for inbound traffic that can
handle a low rate, but once some threshold is crossed, it dies.
Similar behavior when I've tried copying a file over NFS, etc.

I've tried different ports on my switch, and different ethernet
cables. I have the "options processor max_cstate=2" in modprobe.conf.

Any ideas on how to troubleshoot? Thanks!
