Regarding the Skew, I agree that it is harmless...  I have seen that
on several x460 permutations as well, and it does not seem to affect
anything.

However, have you tried passing something like apic=bigsmp (works on
SLES on a similar configuration)???

I know this is FC and not SLES or SuSE, or RHEL for that matter, but
to me, this sounds a lot like the Xen kernel being used with FC5 is
not enabling bigsmp by default...  I saw the same thing elsewhere and
passing apic=bigsmp seems to fix the problem for me...  so your milage
may vary...

Jeff
