The following error on a SMP x86_64 Centos 4.3 kernel 2.6.9-34 ELsmp appears at boot. and causes things to compute faster. Example, a wait(5) should wait for 5 seconds....it waits for 3 or 2.
This was an open bug for that kernel. Has it been patched in the more recent kernel for Centos 2.6.9-34.0.1 ?

should I insert noapic at grub.conf? What will I loose if i do noapic?
