Debian :: 8.2 With XFCE Constantly Freezing

So I'm having troublesome issues with Debian 8.2, one of them being really costly to my productivity. This issue started maybe a month or so back, and has been continuing since. Laptop is a Toshiba C50-B-14D

During every freeze all those happen:

Screen freezes (The whole display becomes frozen, with only cursor movement - Time displayed stays frozen too)No keyboard input (even Cap & Num Lock leds will not dim once pressed)Power button (pressing once will do nothing - I have to hold for an unhealthy shutdown and reboot)Touchpad Input Works (Cursor responses to movement only, clicks/change on-hover do not.) Fans become quiet

Today at 11:46, it happened while just running Chromium. At the time:

*XFCE4 Power Management Plugin
Presentation Mode [on]
Charger was connected

Here is the syslog (I know this isn't useful as it doesn't show what's causing the issue) the freeze happened at 11:46 and 11:57 is when I rebooted back into debian.

I also started noticing an INFO rcu message during startup:
