Package: linux-image-2.6.17-2-686
Version: 2.6.17-8
Severity: important

Hello,

I managed to get a kernel panic when I tried to add a vlan to one of the
slave interfaces in a bond. :-(

With hindsight I probably shouldn't have tried it, but crashes are bad, 
so reporting it now.

Snip from /var/log/kern.log

Ok, closing it with the current Lenny kernel version, please reopen
if you manage to reproduce again.
