6.1-PRE hang with sysctl and sched_ule
Hi, Got this interesting hang on a two way (two physical cpus with htt disabled by machdep.hyperthreading_allowed) smp box during boot. Any ideas? Kernel config is pretty much SMP with most drivers cut and KDB, DDB and BREAK_TO_DEBUGGER added. Sources are from this morning. I can only reproduce this with the ULE scheduler, switching to 4BSD makes the problem go away.
