New UEFI ISO built with old xorriso
Hi,
is there a special reason why
http://cdimage.debian.org/cdimage/unofficial/efi-development/jessie-upload2/debian-jessie-UEFI-testing-netinst-i386-amd64-build2.iso
was produced by xorriso version 1.2.6 which has the GPT CRC bug ?
This bug was fixed by release 1.3.0.
Release 1.3.4 and above brings El Torito boot images to low
block addresses by default. This is assumed to bring good luck.
(Actually there was a half initialized 32-bit register found
in ISOLINUX code a year ago:
http://git.kernel.org/cgit/boot/syslinux/syslinux.git/commit/?id=88d17d136c21b8afb7d27e091cbb1f757ded80df
One may speculate whether this was the reason for all of the
failure reports with high LBAs.)
