Impossible install of 5.4

[Olivier Gautherot]

Hi folks!

I've tried to install 5.4 but can't boot the disk. I see a FreeBSD prompt (the 
master boot selector being a Linux version of grub) but it complains about a 
missing /kernel.

When I check my 5.3 disk with the new 5.4 install, the content of /boot looks 
fine. I tried all 3 options for the bootmanager but none works.

Any clue of what I should investigate? I've installed several versions of 
FreeBSD in the past but never got this behavior.

Thanks in advance

P.S. Please copy me on answers...
