<pre>The booting is too long on any kernels =>4.4 (higher than Ubuntu xenial non-hwe
versions).
The errors in dmesg output are similar to this:
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR*
[CRTC:41:pipe B] flip_done timed out
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR*
[PLANE:35:plane B] flip_done timed out
I tried amd64 and i386 (i686) architectures with the same results. Also I tried
Fedora and some other distributions.
The system information was collected by apport and posted there:
