Hi,
My testcase was indeed one large file. I did not test lots of small files. It would always lockup after said amount of traffic, but only in 10 Mbit half duplex mode. Also, I have the 82557, not the 82558 chip.
The problem looks a lot like what should be fixed in this changelog line from 2.4.9-ac13:
- Work around eepro100 bug with some chip (Arjan van de Ven) versions on 10Mbit half duplex
Only 2.4.10ac11 still had the problem...
