from testing with piglit glsl-vs-texturematrix2 the likely cause
seems that now we use more temp registers in vs than we'v programmed
to SQ_GPR_RESOURCE_MGMT. The commit above increased the register usage
but we should not hang the card anyway in this case.

Don't know how to fix this though, SQ_GPR_RESOURCE_MGMT is hardcoded for now
and to fix this correctly we should probably set the values to max we will
use in a cs. However there's no infrastructure in driver to change values
already (in the beginning) of the cs.
Alos I don't know the exact constraints/dependencies for the RESOURCE_MGMT
things

Narrowing down, as of mesa commit f061524f0737bf59dad6ab9bb2e0015df804e4b5:
This GPU lockup doesn't appear with shaders disabled.
It appears with shaders set to "simplest shaders", and it can be reproduced by
starting a new campaign.

"Simplest shaders" are defined in
http://vegastrike.svn.sourceforge.net/viewvc/vegastrike/trunk/data/techniques/2_ps1.4/default_simple.technique?revision=12869&view=markup
which points to

OK, with the new version after the revert, this should (still) be fixed.  If it
isn't, could you attach the output of MESA_GLSL=dump? (In general, this is
probably a good idea for shader-related issues)

Created an attachment (id=38535)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=38535)
output of MESA_GLSL=dump

Locking up again. I'm using mesa-git at commit
a09a8ec12d76e1fb1583fa99cf9f48246c108d7b.

This is the output of "MESA_GLSL=dump vegastrike -j nothing.mission". This
avoids the game menu in order to minimize output.

According to /var/log/messages, there were 26 lockups in a row.
I'm not sure how useful this output is - my impression was that the lockups
started right after initialisation, but at the end of the dump I still see
initialisation messages.

Created an attachment (id=38540)

working output of MESA_GLSL=dump

For comparison purposes, this is the same output with mesa-git
a09a8ec12d76e1fb1583fa99cf9f48246c108d7b and reverting
acd7c21541110d7ae6b9e63647391f65946e5c5d and
6c0ba32fd1466e8c1700acab3003dc1fe1deb337.

Working nicely. Apparently, there's not much output after the final
initialisation messages.

--- Comment #8 from Nicolas Kaiser <nikai@nikai.net> 2010-09-14 09:42:52 PDT ---
I noticed that I can make some other applications lock up the GPU in a quite
similar way, using MESA_GLSL=nopt:

Celestia locks up on start, but not immediately: Sun gets displayed without
problem, the GPU locks up as soon as Earth should get rendered.
Oolite also locks up on start, as soon as a spaceship should get rendered.

Currently I'm using mesa 9476efe77ff196993937c3aa2e5bca725ceb0b41 and kernel
2.6.35.4 (with Marek Olšák's 10 seconds patch
http://comments.gmane.org/gmane.comp.video.dri.devel/49821 ).

Without MESA_GLSL=nopt both are working without a problem. However, with it
both also lock up using mesa
a09a8ec12d76e1fb1583fa99cf9f48246c108d7b and reverting
acd7c21541110d7ae6b9e63647391f65946e5c5d and
6c0ba32fd1466e8c1700acab3003dc1fe1deb337, as in comment #6.

Removing myself from CC.  This bug is that the radeon driver needs to cleanly
reject shaders at link time that it can't handle.  (incidentally, i915 has the
same issue, and i965 to some extent).

Yay! One week ago it was still locking up, but now it's fixed.
No lock-up any more, working with r600g as well as r600c.
