An SMP kernel boots and runs fine using debian etch and a single CPU. However I do get this in kern.log: Mar 23 10:59:53 ss20 kernel: Kernel command line: root=/dev/sda2 ro Mar 23 10:59:53 ss20 kernel: PID hash table entries: 1024 (order: 10, 4096 bytes) Mar 23 10:59:53 ss20 kernel: start_kernel(): bug: interrupts were enabled early Mar 23 10:59:53 ss20 kernel: Console: colour dummy device 80x25 It looks like something similar was fixed a while back on sparc64 but I don't know if this is related. I'm recompiling a kernel with more debugging turned on to see what happens. I get a hang when booting the same kernel with 2 CPUs at: Begin: Loading essential drivers... ... Nothing interesting before that. Any advice on how to approach fixing these issues? I can test patches.
