We are having problems remounting an ext3 filesystem using an external journal device. The filesystem in question was working fine until the server was rebooted. This is what we see on dmesg when trying to mount: EXT3: failed to claim external journal device. The external journal lives on a LVM2 logical volume and it seems to be accessible ( we can dumpe2fs and see filesystem information).

This set of patches add some support for sector size >512. Currently it fixes extlinux, MBR for GPT and ext partitions. Other code is unaffected. This set of patches has been tested on a read Dell machine running a beta firmware.

Hello, Happy New Year! These patches make syslinux/linux support ext2/3/4, and it doesn't require the root privilege, I'd like to add a separate e2fs/syslinux, if that is more appropriate, it should be easy to do that. I put these patches on github so that you can easily get them in case you'd like to test them. (The repo's name is sys_tmp, which avoids confusing others, I will
