So you are switching the mainboard and boot the system from hdd as usual?
Yes, and have been doing that for years. All I have to do is "rm /etc/udev/rules.d/70-persistent-net.rules" and on the next boot I get new ethernet as eth0 (which is later configured as part of br0, but have tried also without bridge-ing).
In fact, I have configured my system so that it automatically removes that file after booting, so I don't have to do anything when swiching boards.
I suggest that you test new hardware with a LiveCd instead of an installed distro. Problems like that which you are experiencing sound just about right for what you are doing. Motherboards are complex beasts, there is a lot of model-specific software on an installed Linux distro. Not having had problems before in the past does not mean that the procedure is safe. -- Dotan Cohen http://bido.com http://what-is-what.com -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
