We've not seen any issues running mainline kernels
(2.6.30.x at present) with CentOS 5, what issues have
you seen with this ?

2.6.31 also introduces new (better?) support for MCE's
on the k10h family of CPUs (Barcelona, Shanghai), though
if you (like us) have scripts that parse /var/log/mcelog
you'll need to look at the data in /sys instead.

cheers,
Chris
