Subject: [drm:radeon_dp_link_train] *ERROR* clock recovery failed
Date: Thu, 3 Mar 2016 02:38:11 +0000 [thread overview]
Message-ID: <20160303023811.GA31411@milliways> (raw)
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 ?
