Description michel munnix 2006-01-06 15:38:53 UTC

after installing SuSE linux 10 on a IBM Thinkpad A21e (text mode only)
ethernet adapter showed up with mac adress ff:ff:ff:ff:ff:ff
after booting failsafe, it appears with correct mac adress but it is eth1.
There is no eth0.
Yast told something about a duplicate adress ???

You need to specify acpi=off on the commandline (and not use failsafe).
This is a well known BIOS bug of Thinkpads A2x and T2x series.

ok, I'll try acpi=off only on monday. But how can I get the system to forget about eth0 = ff:ff:ff... and get the real mac adress with eth0 and not eth1 ?

Comment 4 michel munnix 2006-01-09 10:31:03 UTC

I tried adding only acpi=off : the ethernet adapter commes up with the correct mac adress but it is named eth1, I realy don't know how to revert it to eth0

Michal do you have a clue?

Comment 6 Michal Svec 2006-01-11 09:39:25 UTC

I guess wrong mac is a driver (kernel) issue.

Read /usr/share/doc/packages/sysconfig/README.Persistent_Interface_Names

The interface name eth1 is a side effect of the acpi problem. This is not a bug. And it is no problem if the interface is called eth1 instead of eth0. You can give it nearly any name you like.
