Decoded it gives
.. bus error 'local node origin, request didn't time out data read mem transaction i/o access, level generic' ..
It will probably boot with mce=off acpi=off pci=conf1
You got some buggy device that causes a bus timeout when its config space is read. The old kernel most likely didn't touch it by luck.
Please add the following patch and send the whole log. This will tell us which device has this problem.
