I can feel your pain. I have the same problems with the radeon drivers.
But I'm using the newest mesa directly from git, so half of it is my
problem.

What isn't my problem is that the kernel is not able to guard against
stuff from mesa which could crash the system. This is an ongoing
nightmare since day 1 until the latest stable kernel. The last problem
was an OpenGL shader extension, what will be the next feature to crash
my system?
