NetBSD riemann 4.0 NetBSD 4.0 (GENERIC.MP) #0: Sun Dec 16 02:23:20 PST 2007  builds@wb29:/home/builds/ab/netbsd-4-0-RELEASE/sparc/200712160005Z-obj/home/builds/ab/netbsd-4-0-RELEASE/src/sys/arch/sparc/compile/GENERIC.MP sparc

I have several SS20 workstations with SM71 and RT626@200. When I try to boot NetBSD on a SS20 that runs more than two processors, system randomly crashes with "watchdog error, NMI interrupt".

I have made some tests:
- system is stable with two RT626 (one dual RT626 or two single modules)
- system is unstable with three or four RT626.

I have tested different hardwares, thus I'm sure that hardwares work fine.
Install more than three processors (maybe only HyperSPARC...) on SS20 and wait.
