Bug#636123: similar issue with 2.6.39.2 from backports

["Valentijn Scholten" <valentijnscholten@hotmail.com>]

I am running into a similar isue with 2.6.39.2. amd64.

Intel DH55TC with a Pentium G6950.

I was running a Debian Squeeze with 2.6.38.2 from backports. Was running 
fine.

I decided to install 2.6.39.2 from backports (apt-get install ...)

It removed the old kernel and installed the new one.

I rebooted, and got a kernel panic about not being able to find the root 
file system.

"No filesystem could mount root, tried:"
"Kernel panic = not syncing: VFA: Unable to mount root fs on 
unkown-block(0,0)."

Since the old kernel was removed, I couldn't boot the system anymore.

I installed Debian Squeeze on top of the not-bootable install and was able 
to boot again.
This is with kernel 2.6.32 coming standard qith squeeze.

Anything I can do to help debug the problem?
