I'm on a Supermicro server, X9DA7 motherboard, Intel C602 chipset, 2x 2.4GHz Intel Xeon E5-2665 8-core CPU, 96GB RAM, and I'm running CentOS 6.4.
I just tried to use yum to upgrade the kernel from 2.6.32-358 to 2.6.32-431.29.2. However, I get a kernel panic on boot. The first kernel panic I got included stuff about acpi, so I tried adding noacpi noapic to the kernel boot parameters, which at least changed the kernel panic message, now I get (transcribed from a photo I took, so please excuse any errors):

First question: can you boot with the old kernel still (by default CentOS 6 leaves a few old kernels around; I want to say the default is 3, but it might be 5, I don't recall, and I don't have a straight default C6 install to check against right at the moment)?
Next question: did you also update the updated kernel-firmware package for the updated kernel?
The first thing I would do is downgrade the kernel and make sure the system is working there; you then will need to very carefully check all your hardware components together that the kernel update should be ok. You mention GPU's; which drivers are you using there? Iterate over all hardware.
Now, I'm going to sound like a broken record here. If you absolutely positively must stay at a point release for whatever reason (and there are valid reasons for this), then you don't need to be running CentOS; it is simply not supported. You either need to pay up for RHEL6 with EUS, or you need to install ScientificLinux 6 (built from the same sources that CentOS is built from, with a different rebranding); the SL team does support getting only critical updates but staying on a particular point release.
