The patch to r8169.c from the netdev patch clearly increases stability
The 2.6.2-rc2 kernel hangs within minutes even on very light load, whereas
2.6.2-rc2-mm2-1 holds up under heavy network traffic repeatably for
over half an hour before it hangs and somewhat longer under light traffic.
It is definitely the RTL-8169 interface since I can not get the kernel
to hang using a different (RTL-8139C) controller connected to the same
Gigabit switch.
After many tests I was finally able to capture an Oops:
