I have what I believe is this same problem while booting FreeBSD from GRUB2 using UEFI (grub2 and FreeBSD set to serial). I was using 12.04's kernel. Should have written down which one, but I had all the updates as of 2013 May 9. I updated the kernel to V3.9RC4 as suggested, and the problem remains.
