Subjectoops in 2.6.13-rc6-git12 in tcp/netfilter routines
Howdy, and excuse me for crossposting - feel free to zap CC to
unrelated, if any, mailing lists.

just gave PeerGuardian a spin on my eDonkey home box and
said box didn't last half a day before oopsing in netlink/nf/tcp
related routines (or so it seems to my untrained eye).

K7800, 256MB RAM, uptodate FC3 running 2.6.13-rc6-git12,
doing nothing but running MetaMachine's eDonkey 1.4.3 QT gui.
PeerGuardian is the 1.5 beta version available from methlabs.org.

Stack is hand-copied from the dead box's console.

<0>Kernel panic - not syncing: Fatal exception in interrupt

If there's need for further info I'd be happy to provide it. For now
the box is rebooted into the same kernel and running the same
PG/eD2k programs, if the issue reproduces I'll follow up on my
own message.

Thanks in advance, ciao,
