Hey, you may close this bug now. After hours of testing, I found out that it doesn't worked because of an outdated BIOS-Version. After upgrading the BIOS, everything worked fine again.
Sorry for the inconvenience, thanks for your tips to debug the problem. Greets, Michael -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
