AMDGPU fail to restore secondary monitor after suspend

Thu May 19 23:11:39 UTC 2016

Hi

I was testing the AMDGPU on the A10-7850k and all seems to work, but
when suspending the machine and then waking up again, i lost my secondary
monitor in both the X11 and the console. xrandr reports only one monitor
connected and only a restart enables the monitor back. I suspect that the
suspend turn off the secondary connector and never turn it on again.

I'm using kernel 4.6.0, slackware-current 64and mesa 11.2.2

Here is the full dmesg since start suspend to the end of the wakeup:

I don't know if this is a new bug or a existent bug or a missing feature
only for the SI support. Reverting back to radeon it works fine.

Naturally the common people don't want war... but after all it is the
leaders of a country who determine the policy, and it is always a 
simple matter to drag the people along, whether it is a democracy, or
a fascist dictatorship, or a parliament, or a communist dictatorship.
Voice or no voice, the people can always be brought to the bidding of
the leaders. That is easy. All you have to do is tell them they are 
being attacked, and denounce the pacifists for lack of patriotism and
exposing the country to danger.  It works the same in every country.
