Looks like that in the latest drm-intel-nighly kernel this bug is fixed.
i did the next step in order to verify this bug since the reproduce steps they
do not say much.
1-remove dmesg log #rm /var/log/kern.log and reboot the system
2-once the system is boot up check the dmesg
I also must comment that i the dmesg has the following parameter in the grub in
order the get more information regarging i915 driver, please check
dmesg_skl.log for more information
initcall_debug
drm.debug=0xe
This is part of dmesg_skl.log :
