>Description:
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.
>How-To-Repeat:
Install more than three processors (maybe only HyperSPARC...) on SS20 and wait.
