Grub update broke booting on UEFI systems, I get a message saying "null in the ring. Aborted. Press any key to exit." I think this is the result of the BITS=8 vs BITS=10, as Kamal mentioned SIZE==2^BITS, setting BITS=8 SIZE should be set to 2^8. The reason I suggested using BITS=8 is that will correspond to the largest supported sector size on the disk, which is 4K sector size. Kamals settings of BITS=10 will read more than one sector at a time, it might consume more memory but might not cause any harm. Since we have already tested BITS=10, I suggested we do what Kamal suggested and what we have tested. Unless someone else has an opposition to reading more than one largest supported disk sector at a time.
