Description:
After installing the 07/01/06 daily of dapper (also same bug in
flight2), when the install wants to restart for the first time just
after installing grub it fails to boot.

When selecting the 2.6.15-11-386 option grub prints this:

----------------------------------------------------
Booting command-list

root(hd1,0)
Filesystemtype is ext2fs, partition type 0x83
kernel /boot/vmlinuz-2.6.15-8-386 root=/dev/hdb1 ro quiet splash
   [Linux-bzImage, setup=0x100, size=0x1534ad]
initrd /boot/initrd.img-2.6.15-8-386
   [Linux-initrd at 0x1fa95000,0x55a218 bytes]
savedefault
boot

----------------------------------------------------

This should happen and then the line similar to:
uncompressing Linux... ok to boot
should apear as it loads the kernel and boots but this does not happen in my case. the cursor just sits there blinking. 

I have reinstalled Dapper over 10 times on 4 differnet hard disks in the
same machine in various partition layouts but it makes no difference.

I installed Breezy onto the disk i want to use and it loads fine. I then dist-upgraded to Dapper. selecting  the 2.6.12-9-386 breezy option boots fine and all packages are dapper packages. Selecting 2.6.15-11-386  again fails to load without any error at all. Both kernel images and initrd images are in the same place so hard disk access is not the problem.
I tried the k7 flavour but no luck....
