The 2.6 kernel seems to run just fine on the SS20 with SuperSPARC?s, but only in uniprocessor mode. If you want/need SMP or have HyperSPARC?s, stick to 1.0. Otherwise there's no known reason to avoid 1.92.

Tested Configurations

Aurora Version Configuration Remarks Reporter
1.0, 1.92 85MHz SuperSPARC?-II, Sun TGX video, 64MB RAM Works fine SMP on 1.0 (until my second CPU died), and UP on 1.91/1.92. Headless via serial. Jima
1.0 2 x 150MHz HyperSPARC?, Sun cg14? video, 192MB RAM Boots SMP everytime, and video works. Adding extra RAM (highmem) reduces the odds of a successful SMP boot. Bob
1.92 150MHz HyperSPARC?, Sun cg14? video, 192MB RAM esp DMA errors, and crashes with cg14 framebuffer Bob
