Comment 1 Rex Dieter 2016-10-23 21:55:19 UTC 
We'll need a more complete backtrace to debug this further.

Comment 3 Rex Dieter 2016-10-24 17:40:07 UTC 
That's all? still seems to be an incomplete backtrace

is nvidia libs/driver involved at all?  (if so, you may need to contact them, we won't be able to debug it)

Comment 6 Rex Dieter 2016-10-25 01:21:18 UTC 
we've received reports of several other users having problems with 367.57 driver release.  most issues resolved by downgrading (to 367.44)
Comment 7 George 2016-10-27 02:36:01 UTC 
Also problems with the rpmfusion 340 nvidia drivers.

That isn't possible as 304xx doesn't use libglvnd!

Should be fixed in version xorg-x11-drv-nvidia-367.57-3

It isn't possible to downgrade using dnf as rpmfusion doesn't keep old versions in the repo.

Comment 11 Sergei LITVINENKO 2016-10-31 19:19:11 UTC 
for x64 rpmfusion provide updated version
Now for me everything is OK...
