Hi, It looks like extlinux's code doesn't have support for the "64bit" feature of ext4: extlinux: struct ext2_group_desc { ... uint32_t bg_inode_table; /* Inodes table block */ ... } ext4: struct ext4_group_desc { ... uint32_t bg_inode_table_lo; /* Inodes table block */ ... uint32_t bg_inode_table_hi; /* Inodes table block MSB */ } I'm seeing an issue where sometimes the syslinux.cfg my userspace code is writing is ending...

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply
