After showing the error message the system starts booting the default kernel, but that entry seems to be hit by another bug: #841426 I fixed the grub menu problem by booting with a live USB and commenting out the lines below in /etc/grub/00_header as described here: http://www.barryprice.co.uk/2012/05/04/fun-with-btrfs/ cat << EOF if [ -s \$prefix/grubenv ]; then load_env fi EOF Other distros seem to be struggling with this bug as well: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/736743 As the bug seems to be related to btrfs, it might be triggered by the fact that I started out with ext4 filesystem (although I'm not entirely sure) on 12.3 and ended up with btrfs on 13.1. Reproducible: Didn't try Steps to Reproduce: 1. Upgrade 12.3 with ext4 filesystem to 13.1 RC1 2. Reboot Actual Results: Grub produces the error message: sparse file not allowed Expected Results: A functioning grub boot menu -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
