I ran top during that time, and there was no significant cpu usage.
Probably interrupt starvation... are there any interrupts being shared,
or does your NIC driver take an especially long time to handle interrupts?

Thank you, Kevin. Removing the ohci_hcd modules on 177 solved the problem.

However:
eth0 isn't plugged into anything. eth0 is assigned 192.168.2.4 while
eth1 is attached to the Internet with a public IP. Both eth0 and eth1
are integrated into the motherboard.
There should be no activity on eth0, so I don't understand why eth0 is
getting interrupts and why there is a problem. Here is lspci for bus #1:
