Problems with FAI 3.2.15 and Ubuntu Hardy (8.04.1)

[Allan Bailey]

I've built and tested FAI 3.2.15 from an ubuntu hardy server (x86_64)
using VMware instances, and they boot and install fine.

With the same vmlinuz and initrd an actual hardware box hangs at
mounting /.  I've tested with break=mount and break=mountroot, and I
only  get the initramfs prompt with break=mount.

The bootlog is here:  http://pastebin.com/m2518c13d

Any help or pointers would be appreciated.
