Please abandon the original patch and try this one: http://people.freebsd.org/~peter/topology.diff This should fix it once and for all. I have tested it on amd64. I have compile tested on i386 (an old laptop), but not booted it on an i386 smp box - I dont have one. As such, I'd very much appreciate any confirmation from i386 users that it works. Both from HTT and non-HTT users. Please check that sysctl kern.sched.topology is right. On an Athlon64 X2 or dual-core opteron, it should be "0". A HTT p4 or xeon should be non-zero. It should be the same in both i386 and amd64 mode. -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5
