Thanks for your report. Due to some reliability problems with GRUB and XFS, you need to use a non-XFS root filesystem or create a non-XFS /boot filesystem. The fact that the partitioner doesn't warn you about this up-front is also bug 47848, and is fixed in dapper-updates. We'll be doing a point release of dapper this week or so to correct this problem.
