Hmm.. No.. I have 4 other touched files, and they have #ifdef 
WORK_IN_PROGRESS around the changes, this is not defined.

Did you rerun config and "make clean depend"?

I ran without APIC_IO and SMP_INVLTLB to start with, and am currently (in 
X11) running with APIC_IO and SMP_INVLTLB.

The other possibility is the difference in kernel configs..  Oh, are you
running P5 or P6?  There is a potential problem with tss descriptor caching
that might have come out in the P6 under SMP..
