Tushar,

Ah, sorry. I thought you were referring to a PCI bridge, or something similar.

The br0 interface contains the eth1 and eth2 interfaces, which each connects to a PC on the private LAN. The eth0 interface connects to the ADSL router, and br0 holds the PC's internal LAN IP address. (eth0, eth1 and eth2 are all e100 interfaces, of course.)

It's impossible to state whether the problem *only* happens when I use the bridge because:
a) I've always used the bridge, and need to for the LAN to work, and
b) the problem is both rare and intermittent, even when it does happen. I certainly didn't notice it with the 2.6.36.2 kernel, nor any of the 2.6.34 or 2.6.35 kernels, although the fact that I did with the 2.6.33.6 kernel suggests it was present in all those kernels anyway.

I'll send you the bridge setup and ifconfig information later; I'm not in front of that PC right now.

Thanks,
Chris
