Net module Realtek 8110S/8169S

Hi Francois,
      Fisrt, excuse for my bad english. I have big problem with module r8169
shipped with kernel 2.6.4. My system is a Pentium4HT, mainborad is a MSI 865PE
Neo2-P with integrated Fast Ethernet Realtek 8110s/8169S (as I see in bios
message). When I transfer a big file (size > 5Mb) from my system to another PC,
it freeze without any message. The
only messages that I see in the log are some line with text "eth0: Too much work
at interrupt!", not at same time with hang. I think is NIC module problem
because  only operation I do is transfer file (with samba client) in tty (not in
X). With kernel 2.6.3 the problem isn't show.
     As you write in README.txt in your site in /linux/kernel/2.6.x/2.6.4-rc2 I
tryed disable SMP and the new fetaure "SMT (Hyperthreading) scheduler support",
"Preemptible Kernel" and ACPI/APM support. But the problem persists.
     With Kernel 2.6.3 I noticed only a thing, if I unplugged the cable and
re-plug the network not respond (not link on NIC). Only if I stop and start then
daemon, network return-up. 
     I have an 10Mbit Hub, but both problem rise if I use a switch 10/100 Mbit.
I can't test with GBit.
I send you 'dmesg', 'lspci', 'lsmod', 'cat /proc/interrupts', 'ifconfig' output.
     For nmi watchdog I don't see the option in kernel menu. If you tell me
how... I'll try...
     I tryed vanilla-kernel and Andrew Morton's kernel.
Any Idea? 

Bye

P.S. I use Gentoo Distribution...
