I think I'm running into the same issue with WebGL. Also searched for IPEHR
number 0x7a000002 and found this report.

System environment:
-- chipset: Intel Corporation 2nd Generation Core Processor Family Integrated
Graphics Controller (rev 09)
-- system architecture: x86_64
-- xf86-video-intel: 2.21.15-1
-- xserver: 1.14.5
-- mesa: 9.2.5-1
-- libdrm: 2.4.50
-- kernel: 3.12.5-1-ARCH
-- Linux distribution: Arch Linux up-to-date
-- Machine or mobo model: Lenovo x220i
-- Display connector:

Reproducing steps:
- Install Chromium Version 31.0.1650.63 (238485)
- Activate new Google Maps with WebGL
- Browse Maps

Took about a minute to recover.
