I Canonical response noted the following from the dump:

[ 42.640541] resource sanity check: requesting [mem 0x000c0000-0x000fffff],
which spans more than PCI Bus 0000:00 [mem 0x000c0000-0x000dffff window]

I've since updated to the latest BIOS at there suggestion.

I see the following on the screen when the kernel crashes:
