Comment 4 for bug 1284196

I'm getting this on actual hardware with a 3TB disk. Same issue with grub.cfg existing in blocks beyond the 2^32 sector limit. An ls (hd0,gpt2)/boot/grub results in the 'attempted to read or write outside of disk (hd0)' error. Seems like most other files on the disk can be accessed by grub AOK.

Mobo is a Gigabyte GA-Z68X-UD7-B3 - couple years old.

Not a big deal for me as I just setup a /boot partition to workaround the issue. Might catch others offguard, though.
