Hi, with 4.1-rc display-port on my Tahiti XT stopped working. I used the firmware from http://people.freedesktop.org/~agd5f/radeon_ucode/ as of today. Note: the display is an Asus PB278, it used to have problems with display port negotiation, but those disappeared like a year ago.
Does booting with radeon.auxch=0 on the kernel command line in grub help? Can you bisect?
Alex
Yes, radeon.auxch=0 helps. As for bisecting, I can try, but I won't have time for that until next week.
No need to bisect. if auxch=0 helps, I know what commit broke it. Does the attached patch help?
