I can build the whole system with -march=native (buildworld), install it and at least run it. But then in multiuser mode, hitting the tab key, always ends up in a forced logout (it is with every shell, but only in multiuser mode, noct when starting the box in single user mode). Well, so far. Thought it was a fair chance, tried to revert what I've done and start compiling the OS again with either -march=core2 ore simply omit this. No chance! Shortly after start building world, I receive a weird error that cc1 failed compiling something, I need to make a report. When switching back to the legacy gcc 4.2, the same error occurs. The system isn't usable anymore. The OS is instable, hitting TAB key always ends up "logged out". I guess the only way to revert this is to install the box from scratch. I tried installing a base system from an installation DVD, it works so far. Oliver
