Hello
Today I updated kernel from git://anongit.freedesktop.org/drm-intel
(SHA130047b32f05df9d6c01531e64ca15a212ee5a83e)
and upon booting my laptop I have error messages

The processor then runs at full frequency.

Here is the system info:

uname -a
Linux localhost 4.17.0-rc3+ #1 SMP Thu Jun 7 18:04:00 MDT 2018 x86_64 Intel(R)
Core(TM) i7-4700MQ CPU @ 2.40GHz GenuineIntel GNU/Linux

and here is how I boot

kernel /boot/kernel-3.0 root=/dev/sda3  init=/usr/lib/systemd/systemd quiet
udev api_osi=Linux acpi_backlight=vendor

Any advice?

Thank you

-Adam
