Default apt-get update, apt-get upgrade, and now system fails to boot

debian-user:

I have an Intel DQ67SW motherboard with Intel i7-2600S processor and
have installed debian-6.0.5-amd64 and the 3.2 kernel from backports.



I ran "apt-get update" and "apt-get upgrade" yesterday. Since then, the
system fails to boot:


Loading Linux 3.2.0-0.bpo.2-amd64 ...
Loading initial ramdisk ...
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/mapper/sda2_crypt does not exist. Dropping to a shell!


Busybox v1.17.1 (Debian 1:1.17.1-8) built-in shell (ash)
Enter 'help' for a list of built-in commands.

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


When I enter "cat /proc/cmdline":

BOOT_IMAGE=/vmlinuz-3.2.0-0.bpo.2-amd64 root=/dev/mapper/sda2_crypt
ro quiet



When I enter "cat /proc/modules", I see many lines of the form:

usbhid 39946 0 - Live 0xffffffffa0153000
...


When I enter "ls /dev/sda*":

/dev/sda /dev/sda1 /dev/sda2


When I enter "ls /dev/mapper":

control


Any suggestions?


TIA,

David
