mount hangs

[Sidik Isani <lksi@xxxxxxxxxxxxxxx>]

Hello -

  I managed to get xfs_repair to clean my filesystem by adding some
  swap space.  It reported no problems.  After that, mount -o ro
  worked fine:

XFS mounting filesystem md(9,0)
Ending clean XFS mount for filesystem: md(9,0)

  but attempting to mount without read-only still hangs, apparently
  indefinitely (there's no activity on the machine.)  The version
  of mount is 2.11u, and we're running the CVS kernel.  It's a bit
  scary to think we're going to have to reformat all our filesystems
  if we need/want to upgrade beyond 2.4.16?  Any idea what is going
  on?  Again, xfs_repair now says this is a perfectly consistent
  filesystem, so this shouldn't be happening.

Be seeing you,

- Sidik
