I'm still running into this issue. I posted more detailed information and the
output of dmesg and journalctl on Fedoraforum, here:
http://forums.fedoraforum.org/showthread.php?t=310633

When my system is suspended and wakes back up, the primary LCD is stuck on a
blank white image and sometimes cannot recover when switching TTY's. Dmesg
fills up with this:
[ 270.115821] nouveau 0000:01:00.0: disp: outp 00:0006:0344: link training
failed
[ 270.122646] nouveau 0000:01:00.0: disp: outp 00:0006:0344: link training
failed
[ 270.123698] nouveau 0000:01:00.0: disp: outp 00:0006:0344: link not trained
before attach

Hardware:
HP EliteBook 8440p, Legacy Boot
Nvidia GT218M (NVS 3100M)

Software:
Fedora 24, latest updates, Gnome 3.20.2
Gallium 0.4 on NVA8
Kernel - 4.6.3-300.fc24.x86_64
