Re: 2.6.X not recognizing second CPU

Just want everyone to know that acpi=off seemed to do the trick. Not
sure why but dmesg still reports that it is using ACPI default. There
are no options in the BIOS for APM, btw.
So, what did we accomplish by setting acpi=off if the kernel seemed to
use it anyway? Does acpi=off inform the kernel that acpi isn't offered
by the bios? T
Attached is the new dmesg:
