AFAIK, this is harmless. Our x460 32-way spits out the same
information. This is part of the TSC synchronization code in Xen during
boot.
(XEN) checking TSC synchronization across 32 CPUs:
(XEN) CPU#0 had -125003 usecs TSC skew, fixed it up.
(XEN) CPU#1 had -125001 usecs TSC skew, fixed it up.
(XEN) CPU#2 had -124997 usecs TSC skew, fixed it up.
(XEN) CPU#3 had -125001 usecs TSC skew, fixed it up.
(XEN) CPU#4 had -125000 usecs TSC skew, fixed it up.
(XEN) CPU#5 had -125000 usecs TSC skew, fixed it up.
(XEN) CPU#6 had -124992 usecs TSC skew, fixed it up.
(XEN) CPU#7 had -124976 usecs TSC skew, fixed it up.
(XEN) CPU#8 had -125022 usecs TSC skew, fixed it up.
(XEN) CPU#9 had -125022 usecs TSC skew, fixed it up.
(XEN) CPU#10 had -125022 usecs TSC skew, fixed it up.
(XEN) CPU#11 had -125022 usecs TSC skew, fixed it up.
(XEN) CPU#12 had -125020 usecs TSC skew, fixed it up.
(XEN) CPU#13 had -125020 usecs TSC skew, fixed it up.
(XEN) CPU#14 had -125019 usecs TSC skew, fixed it up.
(XEN) CPU#15 had -125019 usecs TSC skew, fixed it up.
(XEN) CPU#16 had -124498 usecs TSC skew, fixed it up.
(XEN) CPU#17 had -124498 usecs TSC skew, fixed it up.
(XEN) CPU#18 had -124498 usecs TSC skew, fixed it up.
(XEN) CPU#19 had -124498 usecs TSC skew, fixed it up.
(XEN) CPU#20 had -124498 usecs TSC skew, fixed it up.
(XEN) CPU#21 had -124498 usecs TSC skew, fixed it up.
(XEN) CPU#22 had -124496 usecs TSC skew, fixed it up.
(XEN) CPU#23 had -124496 usecs TSC skew, fixed it up.
(XEN) CPU#24 had 374521 usecs TSC skew, fixed it up.
(XEN) CPU#25 had 374520 usecs TSC skew, fixed it up.
(XEN) CPU#26 had 374511 usecs TSC skew, fixed it up.
(XEN) CPU#27 had 374511 usecs TSC skew, fixed it up.
(XEN) CPU#28 had 374511 usecs TSC skew, fixed it up.
(XEN) CPU#29 had 374511 usecs TSC skew, fixed it up.
(XEN) CPU#30 had 374521 usecs TSC skew, fixed it up.
(XEN) CPU#31 had 374520 usecs TSC skew, fixed it up.
