 Hi Guys,
 
 I have managed to get the SMP kernel to boot, and repeat this 
 successfully, by doing the following - Can someone verify this works? 
 For testing, I'm using the GENERIC kernel with SMP and APIC_IO enabled.
 
 At the FreeBSD 5.1 boot menu, select option 6 to exit to boot-loader. 
 Hit the return key at the prompt to continue booting.  On my system, the 
 kernel now does not hang at the testing interrupt prompt.
 
 Obviously this is still not ideal, but hopefully it will give someone 
 who knows the code/architecture a pointer as to how to acheive a fix.
 
 BIOS settings, btw, do not seem to affect this SMP hang-at-boot - the 
 only SMP setting in my BIOS is to enable MP v1.4 - as my system is a 
 dual PIII, stuff like Hyperthreading doesn't apply.
 
 Cheers
 
 
 Graeme
