The answer to is it possible to work around is dependent on you motherboard, and all evidence points to no. http://www.adriansrojakpot.com/Speed_Demonz/New_BIOS_Guide/APIC_Function.htm has a more detailed explanation. - -Scott -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFJPfPS7FYdPX6+iYRArKSAJ0S5xMcNwGb8ekaCWZ6B7SUj2FRCQCfUO+u sEOHoI21G264nKzCjT4iz1E= =3IlK -END PGP SIGNATURE- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

SMP with ACPI disabled
Hi all... I have a dual Xeon machine that was running fine on all four cores, but then I started getting some filesystem corruption because of dodgy RAID drivers. I disabled ACPI, which fixed this, but now I am down to running on two cores. My question is, is there any way to run SMP (that will give me all four cores) without ACPI?

If you are running on two cores, and you see both in /proc/cpuinfo, then you have SMP enabled. Regards, -Roberto -- Roberto C.

If you are running on two cores, and you see both in /proc/cpuinfo, then you have SMP enabled. I can see two cores in /proc/cpuinfo, but I used to see four, since the processors are both dual core (sorry, I should have mentioned this). I'm not sure if I'm only running on one physical processor or one core from each processor, but I'm definitely only running on two cores, and I was running on four cores before, and the only change I made was disabling ACPI. I have the dmesg output from before (with ACPI) and now (without ACPI) if anyone is interested: http://www.webgenius.co.nz/dmesg-acpi.txt http://www.webgenius.co.nz/dmesg-noacpi.txt Cheers, Matt -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
