This morning, at boot, suddenly no LAN. The boot screen already had some SIOCSIF errors. Solaris booted properly, with LAN.
In a nutshell, eth0 suddenly migrated to eth2, as one and only eth device. Details: This is what I get from dmesg: ...

Now I ask myself WHY !? How can a properly working system suddenly end up with a strange eth2 instead of eth0 ? How does an eth0 recognised in dmesg at boot migrate to eth2; on its own ? Is this a bug ? Uwe -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
