One of my machines is an A10 Kaveri desktop, with a good old VGA connection to the monitor. I've only just started trying to boot any 4.5 kernel on it, but with 4.5.0-rc6 and now linus's tree from a few hours ago (4.5.0-rc6-00018-gf983cd3) I get a blank screen, with no video signal, as soon as it tries to switch to a framebuffer.
Comparing the logs, the first bad attempt had a couple of new error messages, everything else in the logs looked normal - Mar 1 19:31:10 deluxe kernel: [ 2.543163] fbcon: radeondrmfb (fb0) is primary device Mar 1 19:31:10 deluxe kernel: [ 2.654179] [drm:radeon_dp_link_train] *ERROR* clock recovery reached max voltage Mar 1 19:31:10 deluxe kernel: [ 2.654181] [drm:radeon_dp_link_train] *ERROR* clock recovery failed Mar 1 19:31:10 deluxe kernel: [ 2.677142] Console: switching to colour frame buffer device 200x56 Mar 1 19:31:10 deluxe kernel: [ 2.680435] radeon 0000:00:01.0: fb0: radeondrmfb frame buffer device Any suggestions where to start looking, please ? ĸen -- This email was written using 100% recycled letters.
