Its seems to be working for me ok with the sysctl machdep.hlt_logical_cpus variable set to 0. (I wonder why its not by default)
It's not default because the performance decreases with htt most of the time.
# sysctl machdep.hlt_logical_cpus=0 machdep.hlt_logical_cpus: 2 -> 0 # uname -a FreeBSD newns.trigger.net 5.1-CURRENT FreeBSD 5.1-CURRENT #0: Fri Aug 22 19:07:26 EDT 2003 [EMAIL PROTECTED]:/usr/src/sys/i386/compile/NS1 i386
I am running on an Intel s875wp1 server MB.

shouldn't it be starting up a second CPU, for the HTT?
