From a little searching I turned up:

which indicates that this is a problem related to Apple's bios-compatible boot support, so one workaround is to do a native EFI install (which I think is a better option most of the time). I'd suggest using a boot manager like rEFInd.

Otherwise please boot up the machine with nr_cpus=1 (nosmp is also reported to work) and grab a copy of the ACPI tables by running 'sudo acpidump > acpi-tables.txt' in a terminal, then attach acpi-tables.txt to the bug. Also for comparison it might be useful if you did the same from an EFI boot (doing this when running from the installer iso is fine, the ACPI tables won't change).
