Subject: 4.1-rc4 display-port on radeon not working
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.
