Whenever I try to boot a vanilla 2.4.19 on a dual cpu SS20, I get the following:
Rebooting with command: linux 2.4 Boot device: disk:a File and args: 2.4 SILO Uncompressing image... PROMLIB: obio_ranges 5 bootmem_init: Scan sp_banks, init_bootmem(spfn[212],bpfn[212],mlpfn[c000]) free_bootmem: base[0] size[4000000] free_bootmem: base[8000000] size[4000000] reserve_bootmem: base[0] size[212000] reserve_bootmem: base[212000] size[1800] Level 15 Interrupt Type help for more information <#2> ok Some google'ing told me that these are memory related problems. This machine has been running 2.2 flawlessly over the last couple of years. And I know that 2.4 is untable with sun4m and SMP. But I want to try it. It has 3 64 MB "SIMMs": two of the same brand X (called X1 and X2), another one of brand Y. I've tried booting with "mem=192M", no luck. Then I've tried swapping SIMMs. The kernel cannot boot reliably evern with a single SIMM in (although it might boot once in a while out of the blue). Does anybody have any clues/pointers? Phil.
