Just a "me too", I have an SMP system running 8/5/04 current that hard locks randomly. It seems to happen more often when there is moderate I/O load, such as extracting a tar file or compiling a kernel, but it has happened while almost completely idle too. DDB is in the kernel but cannot be accessed as the system is frozen solid (I do not have NMI capability on this machine). I'm using 4BSD scheduler and get the warning about preemption being disabled. I'm currently running with kern.smp.disabled="1" as that is the only way the system is at all stable :( Oddly enough, it seems to be more responsive without the second processor running than with it -- possibly due to preemption being off.
