XFS as initrd file system

["Jason H. Smith" <jhs@xxxxxxxxx>]

Hi.  I'm trying to make an XFS-only system.  The kernel mounts XFS 
filesystems fine, but I'm having problems migrating from an ext2 initrd 
image to XFS.

I've tried 4, 8, and 32 megabyte initrd sizes; and various block sizes 
(mkfs.xfs -b), but I get the same error from the kernel at the initrd 
phase:

  XFS: device supports only 1024 byte sectors (not 512)
  Kernel panic: VFS: Unable to mount root fs on 00:00

This same setup works if I use ext2 as the initrd filesystem, but I do not 
want ext2 in my kernel for something as trivial as initrd.

Thanks much for any thoughts.  My searches got many false positives about 
XFS modules and such in the initrd environment; but that is not my 
problem at all.
