One thing I noticed additionally: I have Radeon DPM enabled, despite my Kernel requiring a boot parameter for that as that's not yet default.
Does the problem also occur without DPM?
BTW, in case your Mesa is built with --enable-r600-llvm-compiler, does the problem also occur if you disable the LLVM based shader compiler with the environment variable R600_LLVM=0 for the SL process?

Since I have no idea when the issue started happening and I can't risk crashing my machine dozens of times, I can't try GIT bisect myself.
That's just not true, see comment #3. Also (to preempt another concern you mentioned on IRC), bisecting normally doesn't require any knowledge of the code.
I was however able to do an apitrace, which also produces the crash when played back.
Unfortunately, I'm not able to reproduce anything like what you describe with that apitrace on my machines.
I crashed my machine 5 times in order to record this.
Five iterations of git bisect would go a long way towards isolating the problem. If you had started the bisection when you reported this bug, you would have isolated the change introducing the problem for you a long time ago, even if you only tested it once a day.
