Sorry, mixing up with xfs_repair -L. If mount doesn't work, then try to 
xfs_repair -L.

Could be. Dave Chinner knows more. I'd say if a newer kernel is 
problematic, try xfs_repair -L first, and keep the output for review. As 
you have a backup anyway, you're on the safe side. I've needed 
xfs_repair often and never had a problem because of it. YMMV though.

Yes, sometimes running it several times solves all problems.

If you can quickly download a "live" CD with an actual kernel, do that 
and try that. If that is problematic, e.g. you don't have access to the 
server, just run xfs_repair -L.
