Yup, 'fraid so. And because you asked so nicely, I've just managed to reproduce the problem having first done "make distclean" and "make oldconfig", followed by "make" :-). (This was with F12's latest compiler gcc 4.4.2 20091027, BTW.) The symptom was the same - a complete system freeze without anything written to the serial console. So it's just a *guess* that it's network-related, but it does always seem to happen while I'm waiting for a web page to load in my browser...

I saw something interesting in 2.6.31.7 about a crash due to fragmentation:

ipv4: additional update of dev_net(dev) to struct *net in ip_fragment.c, NULL ptr OOPS

I'll try applying that patch too, to see if it makes any difference. Along with that other UDP-related thing I noticed:

udp: Fix udp_poll() and ioctl()

Cheers,
Chris
