Comment # 1 on bug 900787 from Takashi Iwai

The message doesn't seem to be related with nouveau.  It's no kernel message
but a message from the boot process, and mentions that it cannot find MBR.  So
maybe rather related with EFI and boot stuff.

But for checking this, try to boot with nomodeset option.

Also, does this happen with the openSUSE released version, too?
