What I did:
===========

Upgraded Aptosid running in a XEN virtual machine from 3.0-4 to 3.1-5, than to 3.1-6 by "apt-get dist-upgrade".

What I expected:
================

Smooth booting after reseting the VM.

What I got:
===========

Error message "grub ALERT! /dev/disk/by-uuid/xxxx does not exit" where xxxx is the uuid of the exiting XEN drive.

Workaround:
===========

3.0-4 boots without problems.

What else so far:
=================

Asking in grub chat, I got the answer that the error message is not issued by grub. Should ask in distro forum (here).

I found out, that the initrd's are different. Some drivers are missing in 3.1-6: eata.ko and all drivers found in drivers/block/paride/...

However, asking the vendor offering the XEN VM, they are convinced that "libata.ko" is used to access the disk which is available in both initrd.

3.1-6 is booting fine on my physical machines Intel-32, Intel-64 and AMD-64.

hdparm:
=======

root@rolf14:/boot/grub# hdparm -I /dev/sda1

Addition:
=========

Here is an exact (re-typed) copy of the xvp viewer screen:

===================================================================

Booting 'Debian GNU/Liux, with Linux 3.1-6.slh.1-aptosid-amd64'

Loading Linux 3.1-6.slh.1-aptosid-amd64 ...
Loading initial ramdisk ...
Loading, please wait...
modprobe: module unix not found in modules.dep
Gave up wating for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/9317e2d2-1a7f-4c0e-b490-bd4f09c60039 does not exist.
Dropping to a shell!
modprobe: module i8042 not found in modules.dep
modprobe: module atkbd not found in modules.dep


BusyBox v1.19.3 (Debian 1:1.19.3-5) built-in shell (ash)
Enter 'help' for a list of built-in commands.

/bin/sh: can't access tty; job control turned off
