I definitely had that problem. Don't remember if it was limited to my t14amd or not. But I recall moving to a mainline vanilla kernel which reduced problem. But be careful with those as I went through a patch of problems with those as well more recently. I am nolonger using that laptop so I can't tell you whether by now its fixed 100% but I believe vanilla mainline did reduce frequency of the problems occurence. https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories. Also make sure your bios suspend behavior is set to linux if you have it. Hope you have current bios as well.

Couple of months later and it haunts again, this time in latest f34 updates. Gee, it really seems like that "fantastic" Lenovo which some Fedora devels prize, of which I have been a customer too and for a while - quite few different ThinkPads - but know I begin to seriously consider a vow - Lenovo? even again and way! away from.
