I have a weird problem lately:
My system only boots if either a CD is inserted (any CD, not a specific CD(*)) or if I enter UEFI-BIOS before boot.
grub2 would start but afterwards the screen stays black.

/dev/sdc, generating a raid-1 out of these two partitions and adding the RAID to
My boot-device however is
/dev/sda (I have a EFI-partition on
If that helps: I run Debian Wheezy (but also have some packages from experimental).

(*) I tried the following CDs:
- A Debian Wheezy Live DVD (actually a DVD, not a CD) => System booted
- A Mini CD which came with my WiFi-Router (so to say a driver CD) => System booted
- Another driver CD that came with my printer ages ago => System booted
- A music CD (Vive la Fête - République Populaire, but I'm quite convinced that doesn't matter) => System didn't boot
It looks like all data CDs work...
here's my dmesg file (with inserted CD)
maybe that helps!?
