Platform: 8530.96.0 (Official Build) stable-channel chell

Steps to reproduce the problem:
1. Use HP Chromebook 13 in docked mode
2. System will soft crash intermittently

What is the expected behavior?
A stable system.

What went wrong?
You can tell the Chromebook is soft crashing because the volume slider pops up every time the system recovers (the volume slider pop up is related to another bug already on the tracker).

Here are the relevant logs:
