GPU panic on MacBook Air (2014) with Yosemite

Question

Hello, my new MacBook Air (system details below) has been having intermittent GPU panics when using Safari. These seem to be correlated with sites on the Gawker network (e.g. http://www.gawker.com, http://www.lifehacker.com) when they play a pop up video ad. Here's a slice of the report from the console:
Event:               GPU Reset
Data/Time:           Mon Dec  8 19:44:05 2014
Application:       
Path:              
OS Version:          Mac OS X Version 10.10.1 (Build 14B25)
Graphics Hardware:   Intel HD Graphics 5000
Signature:           13
Report Data:
===========================================================================
                         Intel GPU Hang Summary
                              version 1.0.0
===========================================================================
-- Summary of Status for ALL Rings --
MAIN Ring is hung in a batch buffer <-- ROOT CAUSE!
MEDIA Ring is idle
BLT Ring is idle
VEBOX Ring is idle
The problem seems similar to this one: Kernel GPU Reset, Yosemite, MacBook Pro 13 Retina Early 2013
Sometimes the system recovers on its own, most recently I had to hold down the power button to restart.
Details of my system:
MacBook Air (13-inch, Early 2014)
1.4 GHz Intel Core i5
8 GB 1600 MHz DDR3
Intel HD Graphics 5000 1536 MB
OS X 10.10.1 (14B25)
Safari Version 8.0 (10600.1.25.1)

Answer 1

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.
