--- Comment #44 from Ortwin Glück odi@odi.ch 2011-05-17 02:45:27 PDT --- But I also noticed the line "radeon 0000:01:00.0: Invalid ROM contents" in my dmesg. Although I am not using EFI boot (plain old grub without EFI support), this indicates that the kernel doesn't see a valid video BIOS, right? So I doubt this bug as anything to do with DP link training actually, and bug 26891 is really the cause.
