More a matter of it just not running. There have been code improvements
in the kernel of late that are allowing us to skip having two compiled
versions. At least this is what I have been hearing. I don't run such an
exotic thing yet.

Well that would have been before I got into Linux.

I got my hands on my first PII dual machine way back, and installed SMP
kernels on it, and then had to send off for a replacement processor
after a co-worker modded the hell out of one of the slot one packages.
I was very happy when the machine still ran with only one CPU.

I think that was SuSE 7.1 or slightly earlier.

I think it depended on a number of hardware issues. Some device drivers
that were correctly written could exercise the problem. I do not think
it was an all-or-none thing. But in most all Linux installs, in the
troubleshooting section, there is always the suggestion that one should
always try the non-smp version of the kernel if there is any problem. I
think this is becoming less and less a troubleshooting step.
