Package: kernel
Version: 2.6.26-12
Tags: lenny

I am facing repeatable kernel oopses when adding a via-velocity driven NIC
to a bridge. The conditions are:

* bridge set up automatically by means of /etc/network/interfaces.
---8<---
auto br0
iface br0 inet dhcp
  bridge_ports eth0 eth1
  bridge_fd 4
  bridge_hello 1
  bridge_stp on
--->8---
* eth0 is VT6120/VT6121/VT6122 Gigabit Ethernet Adapter (via-velocity)
* as soon as eth0 is enslaved the kernel oops
* the same issue occurs when setting up the bridge manually

I am using a custom kernel to circumvent bug #508527 (BTS Bug ID). The
via-velocity driver was diffed and patched against the current git 
version of via-velocity.*

The kernel config is stock lenny.

Hi,
your bug has been filed against the "linux-2.6" source package and was filed for
a kernel older than the recently released Debian 7.x / Wheezy with a severity
less than important.

We don't have the ressources to reproduce the complete backlog of all older kernel
bugs, so we're closing this bug for now. If you can reproduce the bug with Debian Wheezy
or a more recent kernel from testing or unstable, please reopen the bug by sending
a mail to control@bugs.debian.org with the following three commands included in the
mail:

reopen BUGNUMBER
reassign BUGNUMBER src:linux
thanks

Cheers,
        Moritz
