Standard vga text console, also no framebuffer device active.
Hmm.  You really should see something ...

Maybe grub does something silly, so the machine comes up with
the vga in graphics instead of text mode.  What happens if you
turn off the eye-candy stuff in /boot/grub/menu.lst (comment
the gfxmenu line)?

Here is what the start of my menu.lst looks like;

  adler:~ # mount /dev/hda2 /boot
  adler:~ # head /boot/grub/menu.lst

*** STOP PRESS ***

I just put the server machine back in the rack and when
I booted it up, the text console came up with text on it!

** boggle **

However the font was corrupt (little under lines
under all the u's and p's).

** double boggle **

Part way through the font got fixed, possibly when a new
console font got loaded.

This would normally scream flakey hardware to me,
except I have seen the black screen problem on two
different disks and 3 different mother boards (that
is two motherboard and one laptop).

I sincerely hope that I haven't been leading you folks
on a wild goose chase.

yours dazed and confused,

Robbie Dinn
