        Just a question. Is sparc32 smp usable ? I have to install NetBSD 5

support was partially broken and I haven't seen news for a long time.

Try -current, it should mostly work there. No chance for 5.x.

I'm trying NetBSD current (up to date binary sets). MP kernel is more stable than 5.99.24 I have installed from sources a long time ago.

But, when I put more than one processor in this SS20, system randomly reboots without any error on serial console when system is loaded by some running process.

I'm testing with only one processor and I believe that system is stable enough to build system from sources.

Test configuration:

           SMCC SPARCstation 10/20 UP/MP POST version VRV3.45 (09/11/95)

CPU_#0       HyperSPARC ROSS RT620/RT626      0x00080000 Bytes ECache

CPU_#1       ******* NOT installed *******
CPU_#2       ******* NOT installed *******
CPU_#3       ******* NOT installed *******
