My hero!:) I just tried it out on dual CPU Ultra2: scc0: <Zilog Z8530 dual channel SCC> mem 0x1100000-0x1100003 irq 2024 on sbus0 scc0: [FAST] uart0: <z8530, channel A> on scc0 uart0: [FAST] uart0: console (9600,n,8,1) uart1: <z8530, channel B> on scc0 uart1: [FAST] scc1: <Zilog Z8530 dual channel SCC> mem 0x1000000-0x1000003 irq 2024 on sbus0 scc1: [FAST] uart2: <z8530, channel A> on scc1 uart2: [FAST] uart2: keyboard (1200,n,8,1) uart2: keyboard not present uart3: <z8530, channel B> on scc1 uart3: [FAST] It works, but much more important is that I can't deadlock the system anymore when trying to load gmirror, which printfs from two CPUs at the same time. Before this change, the system deadlocked hard every time I tried to load gmirror on this SMP-enabled machine.
