Created attachment 214751 --> https://bugzilla.kernel.org/attachment.cgi?id=214751&action=edit 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.
