Hi,
Bringing the interface down was no issue, but bringing it back up ("sudo
ifconfig eth1 up" in the analogy) gave an instant freeze. Needed to hard
power down the system and reboot. Everything working fine after reboot.
Nothing shows up in the console at all.
I just noticed with 11.04 I don't have a /var/log/messages file per default
anymore. If you can advice me how to log for this issue I'd be happy to do
further testing.
