hyper threading is disabled.
the weirdest thing.. i have a P4 CPU in my machine. it has hyper threading enabled (it shows 'ht'-flag in /proc/cpuinfo, x86info and dmidecode). but it will not enable hyperthreading. /var/log/messages shows kernel: Hyper-threading is disabled at boottime. i boot a SMP kernel, latest centos version (i think that's 2.6.9-42.0.3.ELsmp
i looked at the kernel code and see that the message can only appear if the kernel at least tries to detect hyperthreading so i know i boot the right kernel. but why won't it show 2 processors in /proc/cpuinfo, or top, or anywhere.. is it a kernel HT bug or a BIOS bug? is there anything i need to paste here for people to look at?
