Boot failure after upgrade to wheezy
I have 2 debian virtual machines running under Windows Hyper-V Server 2012.
I upgraded them from squeeze to wheezy.
They can boot with the squeeze kernel 2.6.32-5-amd64 ok.
But they cannot boot with the wheezy kernel 3.2.0-4-amd64.
Loading, please wait.
Gave up waiting 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/8cdd1090-26ac-4767-b975-05fad7d1f554 does not
exist.
Dropping to a shell!

cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.2.0-4-amd64

Adding rootdelay=120 has no effect (other than delaying boot failure...)
root= & UUID is correct and matches exactly the root= & UUID of the working
squeeze kernel.
cat /proc/modules
ata_generic 12479 0 - Live 0xffffffffa0037000
ata_piix 29535 0 - Live 0xffffffffa0029000

ls /dev/hd* /dev/sd* /dev/disk
ls: /dev/hd*: No such file or directory
ls: /dev/sd*: No such file or directory
ls: /dev/disk: No such file or directory
No raid or lvm in use.
root is on Hyper-V IDE 0, disk 0, partition 2 (/dev/sda2)
Rebuilding the initramfs had no effect.
Help is appreciated.
