I got it on a 2.6.24 (going up from 2.6.18ish) :-/  I also too get it
Yeah, exactly the same for me, it cares not about PREEMPT either (the
I found its the autoneg bit and kept meaning to track down the bug.
Alas the Netra I have powered on is 'production' and the users
complain when I reboot regularly and the spare one I have is under my
desk and needs some love and attention.

The workaround I have is just before you configure your NIC's
(assuming you only use eth0) to put in your network startup scripts:

====
ethtool -s eth0 autoneg off
ethtool -s eth1 autoneg off
ethtool -s eth0 autoneg on
====

So for debian, prepend 'pre-up' before those lines.

I apologise to the maintainer of the driver for being lazy :-/

Cheers

Alex
