I LOVE YOU, dude!  I had ... well, let us just say, some frustration with a new system with this mobo until I read your post that the SMP kernel works.

Which is funny, because SMP is turned off, by default, because of some stability issues on one-proc hyperthreaded machines!  On the other hand, the non-SMP craps itself spectacularly on at least one multi-proc machine!?

I just wish I had read your post last week, and not started with such silliness on a Monday. :)

Thanks a bunch, to all who have puzzled over these things before me!
