I would say more like this is a pain in the ass. =) and I'm having a feeling that we will have to switch off from the rtl-8139 cards if nobody is willing to help us.
I have an RTL-8139 on 100MBit/full-duplex and was by concidence copying 110GB of data in roughly 300,000 files, some as big as 1GB, last night. Three systems at once were pumping data into a single P4 1.4GHz with the RTL-8139. The line was floored at 10MB/sec, and it ran for about 3.5 hours. I had no problems at all, and was using the P4 box (which triple heads at high resolution) at the same time. Nothing broke, although it felt quite a bit slower than usual :-)
=) I'm also using rtl-8139 cards at work and I haven't seen this kind of problems but I'm not using 2.6-series kernel in those machines. Good for you that you didn't have any problems.

Kernel 2.6.8-rc1, ACPI and APIC fully enabled, NVidia accelerated drivers loaded and in use by one of the three displays. Now that's what I call a stress test :-) If there's anything outstanding with the RTL-8139 driver, you'd think it would pop out under that kind of load. One interesting thing is you both have AMD processors, and I have an Intel CPU, but that might be unrelated.
If it matters, this is on an ECS P4VXMS board - the RTL8139 is built-in.
Yeah, it might be some sort of a bug which is related to VIA Technologies, Inc. VT8366/A/7 [Apollo KT266/A/333]-chipset and RTL-8139? Hard to say at this point. I'll get some other network cards tomorrow from the office and we will see if there is a difference.
I hope that it's not the mobo (chipset). =)
