kernel BUG at net/core/dev.c:3031! (kernel 2.6.5-rc1)

[Auzanneau Gregory]

Each day, my ISP disconnects my pppoe session. 3 times (03/24, 03/30,
03/31), this produced a kernel bug that don't allow me to start again
pppd without rebooting my computer. I haven't been able to reproduce the
problem manually. The problem started with kernel 2.6.5-rc1. I never saw
it with 2.6.4 and before.

my kernel version: Linux greg-port 2.6.5-rc1 #1 Fri Mar 19 18:29:21 CET
2004 i686 GNU/Linux

Here the bug report in /var/log/message
