--- Comment #10 from Felipe Contreras felipe.contreras@gmail.com 2013-08-04 23:33:34 CDT --- I found the problem; it's the latest Linux kernel; v3.10 works fine, but v3.11-rcX doesn't.
I bisected the issue:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f...
So I revert that patch and there's no crash.
However, there's still the problem that the screen flicks black. It appears to happen each time I move the mouse.
