Does Hyper-Threading Technology cause any problem for Linux Installation and use?

Just a quick question:
Is there anyone installing Linux (Fedora or Debian) on an Intel Pentium 4 machine with Hyper-Threading Technology cause any Installation and usage problem?

Any suggestion will be very much appreciated!

It should be detected as an smp setup.

Havenít heard anyone complain that it causes problems. You can always run a hyperthread pentium 4 system with the standard non-smp kernel, just like you can run multiprocessor systems with the non-smp kernel (but youíll just be running one CPU).

If you are concerned, then turn off hyperthreading at the BIOS level, do the installation, turn hyperthreading back on and then install the smp kernel. I think the smp kernel would automatically be installed during a yum/apt update/upgrade if you followed that path, or at least thatís what happens when you move drives between non-smp and smp systems.

Some days back i did a clean install of Fedora Core 3 on a aSUS P4P800-vm mobo based system with P4 HT processor.The install went without a glitch.......I even compiled a Con Kolivas patched 2.6.11 kernel and that too worked flawlessly with HT on.

Of course search and check if your specific mobo/chipset/processor combination has any known issues with HT under Linux. It can save u some headache.

Good Luck!
