Seent the patch, thanks. Those combos are defined by our product
managers to satisfy the demand for systems with the latest chipset that
can be used with Windows 7. ;-) My job is to make them usable for Linux
and now I run into problemns...

Ack. The segfault thing was the best I could get so far. Other distros
like SLED 12 SP2 just die during bootup. I have to find a way to get
debugger access / serial console working on that system so that I can
find out more...

Thanks
