Your root partition is not at the front of the disc.  These days,
you nearly always want to have the first partition on the drive be
a 50MB /boot partition to ensure that the kernels reside under
1024 cyls.  As your root partition is sda9, I presume it's
towards the end of the disc.  Since it's only 600MB, you can
probably re-partition so that it's sda1 and it'll be happy.

This is particularly a problem with RAID devices which tend to not do
cylindar remapping to try to fit as much space in the cylindars
as possible:

	Disk /dev/sda: 64 heads, 32 sectors, 17378 cylinders

With remapping, the largest disc that you can have in under
1024 cyls is 8GB though, so going for a /boot is a good idea
these days.
