>Description:
I have VIA VT-310DP motherboard with two VIA Eden-N CPUs. Whenever I try to 
boot NetBSD 5.0 RC4 it hangs when detecting second CPU (during NetBSD 
installation too):

If I am booting system without SMP and ACPI support (boot netbsd -12) it loads 
ok, however, only one cpu is enabled. I had NetBSD 4.0.1 earlier with custom 
compiled MP kernel and it worked ok with both CPUs.
>How-To-Repeat:
Boot system with SMP support.
>Fix:
Boot without SMP support
