Can you figure out why the on-disk checksum is non-zero? That should not happen. Is it possible that the kernel patch and e2fsprogs somehow have the wrong struct alignment? Is mke2fs not zeroing out the on-disk data - the error is reporting that bg_checksum on disk is 1 when it should be 0? I suppose it is possible for the patch to just ignore the on-disk data if checksums are not enabled, but we didn't have any such problems in the past...
