--- Comment #33 from MirceaKitsune <sonichedgehog_hyperblast00 at yahoo.com> ---
At last, I found a partial workaround! More precisely, the solution was posted
in #82186 by MWATTT. I must simply export the following environment variable:

R600_DEBUG=notiling

I can confirm that with this, I can freely enable all shaders in Second Life
and get no crash for the first time. Stunt Rally also seems to no longer cause
the freezes. However, the new game that I posted about in the above comment
(One Late Night) still produces the freeze even with this enabled.

Until the problem is fixed in the code, I will add this to my ~./profile file.
Does it disable anything important? I'm also setting the bug back from Urgent
to Major, since at least now there is now an acceptable solution to prevent it
in most cases.
