Problems with lenny

[Nikola Knežević]

Hi,

I'm trying to install lenny/amd64 on a test VM, from fai-server which  
is hosted on lenny/amd64. Installation goes well each time, but kernel  
never gets installed! This is what I see in the fai.log:

Selecting previously deselected package linux-image-2.6.26-1-amd64.
Unpacking linux-image-2.6.26-1-amd64 (from .../linux-image-2.6.26-1- 
amd64_2.6.26-8_amd64.deb) ...
Ok, Aborting, since the bootloader might not handle an initrd/ 
initramfs image.
dpkg: error processing /var/cache/apt/archives/linux-image-2.6.26-1- 
amd64_2.6.26-8_amd64.deb (--unpack):
  subprocess pre-installation script returned error exit status 1

In grub's prompt, there is only memtest86+ entry...

Where should I look for the cause of this error?

Best,
Nikola
