I can reliably hang my system (a MacBook4,1 with i915 video) by running the current version of google chrome (that is v 38.0.2125.111) and accessing the chrome webstore: after a few instants the system hangs with a black screen and I have to hard-reset it.
The current version of chromium (Version 37.0.2062.120) works on this same box and Chrome works on another box with a different video card.
I'm running Ubuntu 14.04.1 LTS (kernel 3.13.0-39-generic #66-Ubuntu, X11 2:1.15.1-0ubuntu2.1) and I've applied all the current updates.
I'm attaching a syslog extract with some BT info collected immediately before I hard-reset the box.
If you can access the box through ssh or vt, please do grab the error
state after first hang after reboot. You can get it from:
compress it and upload as attachment. Thanks.
