Perhaps some useful info:

I updated to 3.2.45-030245 and it booted successfully, but DAHDI didn't come up because of a symbol mismatch.
I ran "sudo dpkg-reconfigure dahdi-dkms" and rebooted back into 3.2.45 and DAHDI came up fine.  So the upstream kernel is working for me.

And so I went back to 3.2.0-44, which booted fine because of the symbol
mismatch in DAHDI (which was reconfigured for 3.2.45).  And re-ran dpkg-
reconfigure on dahdi-dkms for that kernel, and now I can boot into
3.2.0-44 just fine.

It seems like the issue here is a dependency problem between dahdi and
the kernel.  The difference between 3.2.0-43 and 3.2.0-44 was small
enough that it didn't fail to load because of a symbol mismatch but
large enough that it caused some serious system issues that prevented
booting.

Juergen, perhaps you should boot to 3.2.0-43 and add dahdi to the module
blacklist.  Then upgrade to the kernel of your choice and hopefully it
will boot.  Then reconfigure the dadhi package so it gets rebuilt for
that kernel.  Then remove dadhi from the module blacklist and reboot.
And pray.

Title:
  After last Kernel Update (3.2.0-44) system hangs on startup

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  My system hangs when I startup. The login screen shows up, but when I
  try to enter the password, after 1-3 chars the system hangs (keyboard
  and mouse freeze, system does not respond to anything except reset).

  I now started the system with the older 3.2.0-41 kernel and it works.

  I also attach a dmesg-file from a previous startup. The only thing I
  noticed myself are the odd NFSD-messages at the end, which I did not
  find in the newer dmesg (with patch 41 kernel).
