does it help if you boot with: i915.mitigations=off on kernel command line ?
YES, that fix the problem in all kernels with the problem. Thanks.
(In reply to Victor Rivero from comment #2) > YES, that fix the problem in all kernels with the problem. > > Thanks. So, you can add this definitively by adding "i915.mitigations=off" using MCC => Boot => Set up boot system => next => In second screen there is a line named "Append", here put "i915.mitigations=off" before "splash quiet". Click on Finish. So this will be added to your system. Can you please feedback after you done this? Feel free to reopen if you are in trouble regarding this.

I know they are still tracking down more fixes upstream so hopefully it will be fully fixed in a later kernel... but for now that kernel option is only way to get it to behave...

I add "i915.mitigations=off" before "splash quiet" in the file /etc/default/grub and then run the command "update-grub2" and all keep working. Thanks again.
