Ok...if you "upgraded" i386 over amd64...all bets off. Too much can go wrong there. And in this case, the reason bsd.rd worked and the regular kernel doesn't /could/ be because the bsd.rd kernel is completely self-contained -- all tools are in the kernel. The regular kernel uses stuff on the disk, if it pulled in an amd64 program on an i386 kernel...well, unhappy things are expected. Now, if you did a fresh install of i386, then there might be an issue. Or it could be that it's never worked and no one ever tested before. Nick.
