I've pulled the THREAD_ORDER change from my next version of the patch. Seems SMP_MAX is just not ready for prime time yet. One problem that I'm having appears to be that the !NUMA config of the current -mm version also doesn't boot so I haven't been able to verify that. (At least it doesn't seem to make it worse... ;-) Thanks, Mike -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
