Yeah.

Marcus, please try something like this:

- become root

- run

( sleep 10 ; echo t > /proc/sysrq-trigger ) &
ifdown eth0

- wait a minute or so

- reboot

- See if the sysrq-t output made it to /var/log/messages

If it did, please send it as reply-to-all to this email. Try to avoid
wordwrapping it, as many do.

Thanks.
