Tried 107-109 - they are fine in SMP. Noticed one major thing though - up
until 109 the APIC was initialized after the CPU tests (coupling & hlt
instruction etc). In all of these kernels initializing the APIC after the
CPU tests worked OK. In 110 the APIC is initialized just before the CPU
tests and this freezes up the system. What I get is the APIC initializes,
the 386/287 coupling tests ok then the hlt instruction test seems to
actually Halt the CPU. ?? I do not know enough about APIC's etc. to know
why this may happen but it also only happens when I compile the kernel

If anyone would like me to test anything - or could point out how I can
reverse the boot sequence to test this hypothesis - I would be happy to
try. Thanks!
