Hi,

I have two machines running FreeBSD amd64 8.0-Stable with custom kernels.
My newer box has had troubles with ssh from day one.
I hoped a kernel upgrade would help, but it didn't.
When I'd ssh into the box ssh would exit with errors:
Bad packet length xxxxxx
Disconnecting: Packet corrupt.

after issueing: "ifconfig em0 -rxcons" everything was stable again.
First I figured it'd be a driver issue. However, I use the same NIC in
my other box!
What could be causing this problem?
