for the failure,
 klog: HIGH Kernel message: [    0.000000] ACPI Error: Gpe0Block - 32-bit FADT 
register is too long (32 bytes, 256 bits) to convert to GAS struct - 255 bits 
max, truncating (20131115/tbfadt-202)

is due to the setting length of GPE0 Block is 32 bytes, over the kernel 
expectation(255 bits).
GPE0 Block Length : 20 ==> 32bytes

 So kernel sent the warnings and truncate it to 255 bits.
this is the bug from ACPICA, and a fix patch has sent to upstream.

Fortunately, it might not impact a lot, and fwts has been lower the
issue to medium.
