I suspect the SMP logic in 2.4.26 is a decade older than the hardware. SMP was pretty unusual then, multi-core was just not an end user feature. I don't doubt that the IO-APIC may have unsupported features. Might I suggest that you boot off a recent "live CD" like Fedora or Puppy Linux, just to see if you still see a problem. If not, you will have more information to evaluate your next step. -- Bill Davidsen <[email protected]> "Woe unto the statesman who makes war without a reason that will still be valid when the war is over..."
