>Description:
When I install more than one CPU (ROSS RT626 or SM71) in SS20, system randomly reboots. Kernel is more stable than older kernel I have tested (5.99.24) but not stable enough to build NetBSD from sources with 'make -j4'.

If there is only one CPU in the same SparcStation, system is rock solid.

When system reboots, there is no message on serial console. Older kernels crashed with 'Watchdog reset' or 'NMI...'. This kernel only reboots and I don't know how investigate.
>How-To-Repeat:
Install more than one CPU in a SparcStation (Ross as problem is easier to reproduce) and rebuild NetBSD from sources with make -j4 for example.
>Fix:
Don't use NetBSD/Sparc in a SMP workstation.

 i believe that the problem is related to savefpstate() IPI.
