            Bug ID: 91197
           Summary: Radeon Trinity 7400G fails with 4K UHD screen -
                    atombios stuck exeuting BF64
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: dennis.jansen@web.de

I have several issues trying to connect a 4k display to the radeon card via
HDMI (@30Hz). If I boot with the screen connected, when trying to take over
modesetting from EFI, the internal notebook display goes black as well as the
external.

When I try to attach it during runtime, I can see the 3840 mode, but when I
tryt to select it I get 
[   97.667521] [drm:atom_op_jump [radeon]] *ERROR* atombios stuck in loop for
more than 5secs aborting
[   97.667549] [drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck
executing BF64 (len 962, WS 0, PS 0) @ 0xC1A1

Switching back to 1920 works fine, trying again simply causes the same error
again. Tested Linux kernels 4.1.0 and 3.19. Ubuntu 15.04.

I might not be able to test for long, will probably send the screen back before
long if I can't get it working in full resolution at all.

I've found a workaround:

xrandr --newmode "3840x2160_30"   262.92   3840 3888 3920 4000   2160 2163 2168
2191  +hsync 
xrandr --addmode HDMI-0 "3840x2160_30"
xrandr --output HDMI-0 --mode 3840x2160_30

I'm guessing the pixel clock might have been too high. Same problem with the
Windows driver. The page (http://www.epanorama.net/faq/vga2rgb/calc.html)
allowed me to convert the modeline with lower clock created with cru
(http://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU) in
Windows to Linux. I was pleasantly surprised to find even vdpau working well,
of course only up to FullHD video, but smooth playback on 4k resolution.

Could you clarify? What was updated? How was it fixed? 
Because the bug is still present for me in 4.2.
If it was fixed for you, maybe you had a different bug. As this is the bug I've
created, I'm reopening it.

Update: I get the BF64 error each time I switch between X and console. So it
takes about 5 seconds each time. I still have to manually had modes to get 4k
to work.
