Desktop freezes

[Mike Chambers]

Clean/fresh install of F22 with KDE last night, and up to this point, 
the desktop has frozen solid about 3/4 times now, as in no mouse, no 
keyboard, nothing.  Have to do a hard reboot to get it working.

Nvidia graphics card with nouveau driver (no nvidia drivers)
Kernel-4.0.0.1 (latest)
All latest updates installed.

Its frozen during System Settings, using evolution email, or just 
starting to open a browser.

Has this already been noticed or reported before by chance?
