dmesg for 4.4.0
Look here: [ 24.114256] Bluetooth: BNEP socket layer initialized [ 35.249644] Console: switching to colour frame buffer device 170x48 That seems to be the "black period" After Bisecting the Kernel I got the commit that introduces the extra 40s Xorg delay: 8c70e1cda04b966b50ddfefafbd0ea376ed8edd5 is the first bad commit commit 8c70e1cda04b966b50ddfefafbd0ea376ed8edd5 Author: Alex Deucher <alexander.deucher@amd.com> Date: Fri Oct 2 16:52:58 2015 -0400 drm/radeon: restore the fbdev mode in lastclose restore the fbdev state if a drm app like X is killed.

I open another Bug for the Kernel delay stuff, think this are two separate bugs. Compiled 4.7.0-rc2 today and it is fixed in there. |
Created attachment 214751 [details] Xorg log for 4.4.0 kernel Hi there! I'm running Debian testing with kernel 4.5.0-1-amd64. Before this I ran Debian Jessie with 3.16.0-4-amd64. After upgrading to testing I noticed a highly increased boot delay of roughly one minute (that was already kernel 4.4.0). In Xorg log I can see that there is three times a gap of about roughly 12 seconds (maybe because my card has three connectors [HDMI/LVDS/VGA]?). When the kernel loads the radeon module there is also a long "black period". Now I found out that by setting radeon.dpm=0 the delay is gone- together with power management.
