OK looks like this problems definitely a grub + xfs /boot thing, it's been observed and confirmed in debian bug reports:
re: http://bugs.debian.org/243835 ----- The debian installer can install a system with / or /boot on XFS. When it tries to install grub on such a system, the grub-install run hangs, seemingly forever. The last thing output is "Probing devices to guess BIOS drives." The cpu is pegged too. This has been reproduced on more than one machine, and I found something that looked like the same problem on google. I've seen it with both the 2.4.25 and 2.6.5 kernels. We have put a guard in d-i to deal with this, it warns users that XFS /boot (or root) will not work with grub. This is not an ideal solution, users want to use XFS for these partitions. ----- Perhaps something similar should be done here? -Jesse -- Ubuntu 6.06 installer crash - Bootloader config? https://launchpad.net/bugs/54139 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
