Yep, practically all instances of this problem were
with the e100. Unfortunately, the current version
of the driver no longer has NAPI as a dynamically
tunable parameter via ethtool. It can be disabled
via a kernel config parameter (CONFIG_E100_NAPI).
You could recompile and see if the problem disappears.
(Not a real fix).

I'd be very interested if you could switch to tg3
on the other box too, and see if you can reproduce
the problem. It all depends on the traffic, phase
of the moon, etc..

Your sysctl settings would be helpful, too..
