_correction_ to my previous mail, this does _not_ happen with the eepro100 driver. (sorry for the confusion, i got the kernel images mixed up with all the testing i've been doing.)

could this affect the e1000 driver as well?

This tends to be checksum
offloading not working as it should or the like. Can you repeat this
with bulk ssh traffic?

yes, with various strange effects:

Received disconnect from 195.58.172.154: 2: Bad packet length 919251405.

or

Received disconnect from 195.58.172.154: 2: Corrupted MAC on input.
