2.6.10-rc3 has appeared to have "fixed" it, although I wasn't all that
sure what caused it in the first place. I'm running 2.6.10-rc3 on both
the main host and the Qemu virtual PCs.

I've been playing with the set up for the last couple of hours. I now
have 5 Qemu virtual PCs with 3 virtual NE2K NICs / 3 real host tun
interfaces running - at total of 15 host tun interfaces. I've now got
them interconnected via 6 separate (internal) bridges.

The 5 Qemu instances are all now running OSPF, the main host (ubu),
where the Oops occured, is also running OSPF, and is attached
to the topology via bridges br1,3,5 and br1,4.

I'll leave it running overnight in this configuration to see how it
goes.

Thanks,
Mark.
