Kernel 2.6.27.7 runs into Kernel Panic on Shuttle X27D with Intel Atom 330

["Ivo Rössling" <ivo@wettinet.de>]

Hi, there!

I experienced a kernel panic when trying to install the OpenSuSE 11.1
[x86-64] on my new Shuttle X27D with an Intel Atom 330.

The manual of the Shuttle X27D is not all too verbose, so I cannot say
much about the chipset or BIOS yet. (But I might find out whatever may
be important. It's just that I don't have it at hand right now...)

When I boot the Install DVD of OpenSuSE [x86-64] and chose "Install"
without changing any option, I run into the following error:

I tried to update my BIOS to the latest version provided by Shuttle.com,
which itself was successful. Unfortunately that didn't help anything.
I also tried the hint posted in one of the SuSE-forums to use the the
network installation. But that didn't help either...

On some webpage I read that the network device of the Shuttle causes
kernel panic on MacOS, so I disabled it in the BIOS. Unforunately that
didn't help either. Only the error changed slightly a bit:

I should finally note that the kernel panic did NOT occur when trying to
install OpenSuSE 11.0 [x86-64] (which is running a 2.6.25.5-1.1 kernel)
or OpenSuSE 11.1 [i586]

P.S.: I'd like to be personally CC'ed the answers/comments posted to the
