Follow-up Comment #1, bug #29940 (project grub):
This bug seems to be caused by the "Disable amd64" commands in
i386/relocator_asm.S
I tested with a 440BX bord, and if I comment out the 4 instructions under the
"Disable amd64" comment, multiboot kernels boot correctly. If I leave those
instructions in, it causes a reboot when trying to boot a kernel.
According to Intel documentation a general protection exception is generated
if the assembler command 'rdmsr' is used with a unimplemented MSR address.
