We've just gotten an Asus P4T533-based machine with a 3.06GHz P4 CPU, bios version 1005. (P4T533 is i850e-based.) The bios claims that the P4 has hyper-threading, and as you can see from the cpuinfo output below, "ht" is among the flags. (And the manual says that P4T533 is ht-enabled.)
I've tried booting with acpismp=force and without, and it doesn't seem to make much difference: Linux still only sees a single CPU. I've also tried 2.4.21-pre4 and -ac4, which doesn't seem to make any difference, either.
Anybody got any ideas why I can't get this to work?
