        <pre>Hi

I am trying to use radeon driver git (38797a33117222dadbc89e5f21ed8cd5deef9bea)
together with 2 radeon cards under Linux 64bit.

# uname -a
Linux denis-devuan 4.6.0-0.bpo.1-amd64 #1 SMP Debian 4.6.4-1~bpo8+1
(2016-08-11) x86_64 GNU/Linux

# lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus
LE [Radeon HD 8830M] (rev 87)
04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus
LE [Radeon HD 8830M] (rev 87)

It works until I try to rotate one of outputs.
$ xrandr --setprovideroutputsource 1 0
$ xrandr --output DisplayPort-1-1 --auto
$ xrandr --output DisplayPort-1-1 --rotate left --left-of DisplayPort-0

Right after attempt to rotate rotated output hangs. The other one still works
though.</pre>
