Hyperthreading detection issue
All, I'm running SuSE 9.3, with all the updates made (Linux zarahemla 2.6.11.4-21.8-smp #1 SMP Tue Jul 19 12:42:37 UTC 2005 i686 i686 i386 GNU/Linux). I have motherboard that supports Hyperthreading and an HT Processor. However, SuSE still does not use both processors. dmesg shows the following: zarahemla:~ # dmesg | grep -i cpu Initializing CPU#0 CPU: After generic identify, caps: bfebfbff 00000000 00000000 00000000 0000041d 00000000 00000000 CPU: After vendor identify, caps: bfebfbff 00000000 00000000 00000000 0000041d 00000000 00000000 CPU: Trace cache: 12K uops, L1 D cache: 16K CPU: L2 cache: 1024K CPU: Physical Processor ID: 0 CPU: After all inits, caps: bfebfbff 00000000 00000000 00000080 0000041d 00000000 00000000 Intel machine check reporting enabled on CPU#0.

Brought up 1 CPUs powernow: This module only works with AMD K7 CPUs And. zarahemla:~ # dmesg | grep -i mother SMP motherboard not detected. "top" and "hwinfo" also support that only on CPU is loaded. However, if I put in a Knoppix disk, both CPUs are detected, loaded and usable. I have an ASRock motherboard. Is this a bug? Am I doing something wrong? Thanks for any help you may be able to provide. -B

Is HT enabled in your bios? Is your memory compatible with HT?
Yes, to both... It's set in BIOS and memory is compatible. Like I said without changing anything, the Knoppix disk detected 2 CPUs without a problem. Any other suggestions? -B -----Original Message----- From: Bruce Marshall [mailto:bmarsh@bmarsh.com] Sent: Sunday, August 28, 2005 9:29 AM To: SLE Subject: Re: [SLE] Hyperthreading detection issue On Saturday 27 August 2005 09:31 pm, Brandon Rogers wrote:

Either this is the wrong list on which to post this question, not a common problem, or a combination of these. I'm almost sure, now, that this is a bug. Does SuSE have a bug reporting site? I looked on the site, but couldn't find anything. I would think that this would be important... -B -----Original Message----- From: Brandon Rogers [mailto:blrogers@ieee.org] Sent: Saturday, August 27, 2005 8:31 PM To: suse-linux-e@suse.com Subject: [SLE] Hyperthreading detection issue All, I'm running SuSE 9.3, with all the updates made (Linux zarahemla 2.6.11.4-21.8-smp #1 SMP Tue Jul 19 12:42:37 UTC 2005 i686 i686 i386 GNU/Linux).

bugzilla.novell.com It could be an acpi problem, have you tried booting with acpi=oldboot as boot parameter?

Bug or a hardware issue? HT works on every HT capable machine I have here (about 4 of them) But all of them are Intel boards.
