GDB backtrace and register info of the crash

For the first time ever, since I'm having a PITCAIRN GPU I was able to run a
full Piglit quick test without crashing my X (hooray for that). During the test
I came across two similar crashes in
"spec/EXT_texture_array/fbo-generatemipmap-array RGB9_E5" and
"spec/ARB_framebuffer_object/fbo-generatemipmap-3d RGB9_E5" (see the attached
GDB backtrace; the backtrace is for
spec/EXT_texture_array/fbo-generatemipmap-array RGB9_E5", but the second
crashed in the same function on the same line and as it's the same format, that
is tested, I guess, these are related, if not, I'm happy to provide a backtrace
for the second case as well and split the bugs).
I can't tell whether this is a regression or not, since this was the first time
I was able to run Piglit on this machine without getting a corrupted results
file, due to the crash of the X server.

My graphics stack is:
GPU: "PITCAIRN" (ChipID = 0x6819)
Linux: 3.13.6
libdrm: 2.4.52-1
LLVM: SVN:trunk/r204517
libclc: Git:master/1e278a7b04
Mesa: Git:master/4c79f088c0
GLAMOR: Git:master/a4fbc7732a (Standalone)
DDX: Git:master/ea6d0affe5
X: 1.15.0-2

Let me know if you need further information.

Oh, nice to hear! Do I need just that patch or the entire series? And what
about Brian's remark regarding memory consumption? Am I about to totally trash
my performance, if I apply this patch/series or is this path hit only rarely?

In theory, yes, you will need more memory. I'm going to rework the patch, but
not today.

Ok, then I'll wait. Let me know when there's a reworked version and I gladly
test it.
