Hello.
After upgrading the kernel to 4.20, I noticed that the boot time
increased from about 5 seconds to 25 seconds. My machine is an Asus
K53SV with an Intel i7-2630QM, i.e. Sandy Bridge. I have an external
display connected to it via HDMI. If the display is unplugged when
booting the machine, the boot time stays at its old value.
The kernel log shows two messages like this :
[ 15.747206] [drm:drm_atomic_helper_wait_for_flip_done
[drm_kms_helper]] *ERROR* [CRTC:39:pipe A] flip_done timed out
[ 26.198968] [drm:drm_atomic_helper_wait_for_dependencies
[drm_kms_helper]] *ERROR* [CRTC:39:pipe A] flip_done timed out
Which are the only ones that don't appear in 4.19.2, where the boot
time was smaller. Bisecting the commits between these two versions
leads to commit 516a49cc19467e298d08a404f73a6e311f4548d1.
Let me know if you need more information.
Kind regards,
Daniel

Small omission on my part : I meant 4.19.12, not 4.19.2 as the last
working version.
Also, I can confirm that reverting
13947d150bae871bd880565ada318b0bcd0e690e from the current HEAD of
linux-stable fixes the issue.

I should really get to bed ... of course, I meant

Hrm. With SNB I would be tempted to blame the LP3 watermarks, but
4.20 already has commit 21556350ade3 ("drm/i915: Disable LP3 watermarks
on all SNB machines").
Can you file a bug at
https://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/Intel
and attach the full dmesg from the boot with drm.debug=0xe passed to the
kernel cmdline?

I submitted the bug report at
https://bugs.freedesktop.org/show_bug.cgi?id=109245 . The dmesg log is
attached to the bug report.
