What the others said, please do an uprade sooner rather than later. 8.0.2 is rather old and since it's an unpatched release contains a few annoying bugs... your NetApp partner should be able to tell you more about it and help you upgrade your system.
The hardware in question isn't, by chance, a FAS3140? We had similar problems with a few 3140's once which were only fixed by upgrading everything to a more recent version (OnTap, BIOS, disk/shelf firmware, etc.)
PCI error and nested machine check exception indicate possible hardware issue. You should contact tech support and ask the solution. Although machine check errors are brought by hardware issue in general, some of them are sometimes fixed by improving firmware and drive in later Data ONTAP. BTW, boot message shows "IBM Data ONTAP 8.1.3P3 7-mode".
