Subject: Re: [PATCH 4.4 00/37] 4.4.110-stable review

Hi Greg,

I cloned and built suse12, and it does not have issues with EFI + PTI
(kaiser) on my machine.

BTW, i have also reproduced this problem on another machine with the
same configuration, therefore, it is not specific only to one box.
Also, as I mentioned earlier I am seeing the same issue with 4.1 +
kaiser patches taken from 4.4.110.

Thank you,
Pavel
