Hi, sorry to ask for yet another sponsoring so soon. Two days ago upstream merged the fix for allowing extlinux to boot from ext4 filesystems with the 64bit feature enabled, which I'd like to get uploaded soon.
With the patch applied, I can no longer reproduce the ext4+64bit problem, so I'm confident the fix works. Booting from ext2/3 and btrfs still works fine. I've updated syslinux in our git repository accordingly: https://anonscm.debian.org/git/debian-cd/syslinux.git Apart from the ext4 fix, I've also dropped my own patch for linking against the newer gnu-efi version in favor of the cleaner one that was proposed upstream. I've set urgency to medium this time, as I don't want to delay the creation of testing images not suffering from Bug #857597 [1]. Thanks Lukas [1] https://bugs.debian.org/857597
