You're getting a bunch of machine checks, the last one of them being
fatal (Process Context Corrupt bit is set) causing the machine to panic.

Tony will probably be able to help you further in decoding what exactly
those MC0_STATUS and MC5_STATUS values mean. <tease>Well, if we had MCE
decoding in the kernel that would've not been an issue... :-)</tease>
