suspend/resume broken on Thinkpad x230

I'm using pkgbase to upgrade system running on this laptop and 
unfortunately, since it took some time for me to notice the issue, I 
don't have a good BE available to check a good commit hash before 
problem was introduced.

It's running Wayland and Sway and when I resume graphical interface is 
so slow that I am not able even to type my password and leave screen 
lock.  I could SSH into it and noticed load avg was high, I also listen 
fan is in high speed but system is so slow that I couldn't collect much 
information.

My system is now running main-n276047-0849f1634a70.

Another user reported same problem on his thinkpad x270 laptop.  He is 
running Xorg.

His broken system is running main-n276084-2f1f523a45fb and latest good 
version was main-n276005-91d8ee3579ef.
