I've just built 3.15.0-rc2 on this box, and discovered that I get a blank screen. The boot appears to complete (it sends me information from SMART which is from my last bootscript), and it responds to MagicSysRQ to reboot. I tried to login and run startx, but that didn't seem to make any difference - possibly something went wrong, it wasn't in my history when I booted a good kernel.
This machine uses a regular old VGA cable to connect it, the following lines in dmesg make me think it has chosen the wrong connector: Apr 21 19:32:45 bluesbreaker kernel: [ 1.273246] [drm:radeon_dp_link_train_cr] *ERROR* displayport link status failed Apr 21 19:32:45 bluesbreaker kernel: [ 1.273247] [drm:radeon_dp_link_train_cr] *ERROR* clock recovery failed Apr 21 19:32:45 bluesbreaker kernel: [ 1.295116] Console: switching to colour frame buffer device 85x34 On a boot with 3.14.0 and earlier I get a different console size - Apr 21 20:42:44 bluesbreaker kernel: [ 1.445992] Console: switching to colour frame buffer device 133x54 My console font is 12x22, and my screen is 1600x1200 but it looks as if 3.15-rc2 has fallen back to trying to use 1024x768. I'm attaching what look like the relevant parts of the messages from the system logs for 3.15-rc2 and 3.14.0. Any ideas, please ? This is an AMD A4-5300 APU and not the world's fastest machine for bisecting :-( ĸen -- das eine Mal als Tragödie, dieses Mal als Farce
