ubuntu server 8.04: BUG Message when starting

[Fuse314]

Yesterday I upgraded my trusted virtual ubuntu server (using Microsoft Virtual Server) from Ubuntu Server 7.10 to 8.04. The upgrade with do-release-upgrade went seemingly ok, but after the restart it hung with the following message (after "Loading GRUB...":

BUG: Int 6: CR2 00000000

Today I tried to re-install the system using the downloaded 8.04 Server, after the setup process finished and restarted the system I have the same error message.

Does anyone else have troubles with booting into 8.04 server?

Any help appreciated.
Thanks

I just tried pressing [esc] when "Loading Grub" is displayed, the menu appears, but starting the server using (recovery mode), it throws the same error (see OP)

Hey I have this exact error when my virtual Ubuntu 8.04 Server boots after install. Did you ever find a fix for this?
