Comment # 3 on bug 943548 from Reg Proctor

Hmm, it is the latest kernel, I'm not sure where I gave the impression I had
moved to using an older kernel. Sorry, if have the latest updates of
everything.

The workaround I gave previously is to stop the errors: 

  "[drm:radeon_crtc_page_flip] *ERROR* failed to pin new rbo buffer before
flip" 

which it does. Without it the errors just never stop.

Also, that change has the additional effect of reducing these errors:

   "(WW) EDID timing clock 241.50 exceeds claimed max 225MHz, fixing"

to just a few on start up. A few meaning around 10 or so all at once and then
they stop. Before the workaround there were hundreds and from memory they were
on-going.

However, when I did that workaround I thought it had fixed the display issue I
have had at: 

 
https://forums.opensuse.org/showthread.php/509011-Weird-Xorg-or-windowing-problem

but that's proven over the last few days to not be the case so those issues I
suspect are unrelated. I guess I should separate that display issue out now
into a different bug report.
