I fixed VDrift with commit 347c00c46e9ecf858a8c21abf58a706b658b5b37 just 2
hours ago. Have you tested the commit?

After updating today VDrift got fixed, but Nexuiz and Sauerbraten are still
bad.

dmesg contains lots of these after Sauerbraten:

The only map I found so far to be problematic is venice, but the CS reject also
happens when I press <ESC> to get to the menu, and select something (except for
'editing...' and 'about...').

This looks like bug #28459 which is already fixed with newer kernel.

I've been using 2.6.33.1 kernel, but after reading the conclusion of bug
#28459, I upgraded to 2.6.35-rc6. Now Sauerbraten venice is OK, however, Nexuiz
is still problematic. It says:

[  929.906079] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!

if I look at certain directions on most maps, but in Desert Factory, for
example, all directions are bad.

An offtopic sidenote: I needed to downgrade back to 2.6.33.1, as both 2.6.34
and 2.6.35-rc6 hangs after an hour or so. It suddenly freezes, and only the
reset button is working.

I recall I was getting "Failed to parse relocation" on a PC with very little
RAM and VRAM. I have no idea why, though.

Now I tried vdrift again with texture size set to large, and most parts of the
track are flashing and a series of this appears in dmesg:

I also noticed that the kernel hang I wrote about in comment 11 happens shortly
after such CS rejects happen. It's interesting that .33 can survive that...

[Bug 28995] [r300g] dri rejects command buffers

--- Comment #15 from Marek Olšák <maraeo@gmail.com> 2010-08-07 15:47:10 PDT ---
It looks like you don't have enough memory and the memory manager is fighting
with it. Nevertheless, r300g should not submit a hardlocking CS no matter how
much memory you have. I'll see what I can do.

might be helpful or you need to increase AGP aperture in BIOS if you can.

also it might be worth trying to boot with radeon.agpmode=-1 as a test.

I tried the patch. It improves the situation a bit, but does not solve the
problem. After increasing the agpgart from 64MB to 256MB vdrift runs correctly
even with texture size set to 'large'. I also tried sauerbraten and nexuiz, and
both seem to be ok. After these tests I wanted to report the result, but the
kernel (2.6.35-rc6) crashed, so I think the deadlock problem still exists.

What deadlock problem? Did the 3D driver cause a hardlock or did it freeze when
no 3D application was running?

After running the above mentioned games with r300g and a kernel newer than
2.6.33, the kernel freezes completely. Not necessarily during the game, often
shortly after closing it. If I don't run any of them, 2.6.35-rc6 works fine,
thus I suspect there is a correlation. I might be wrong, though...

About other running 3d applications: I use compiz with mesa 7.8.2 installed.
Should I try with a non-compositing wm?

I now tried with 2.6.36 and mesa git from nov 12.
vdrift 2009 release with large textures on monaco: [drm:radeon_cs_ioctl]
*ERROR* Failed to parse relocation -12!
vdrift 2010 release with the same settings: OK
sauerbraten with venice map: OK
nexuiz with desertfactory map: [drm:radeon_cs_ioctl] *ERROR* Failed to parse
relocation -12!
doom3: I couldn't test, because since I increased GART from 64MB to 256MB, it
segfaults immediately with:
  WARNING: vertex array range in virtual memory (SLOW)
  signal caught: Segmentation fault
  si_code 1
  Trying to exit gracefully..

Meanwhile I found out what caused the hardlock: the preemption model was set to
preemptible kernel, now with voluntary kernel preemption it seems to be stable.

nope, it's i686 on a pentium 4, which is not 64bit capable

I now tried nexuiz, sauerbraten, alien-arena, doom3, quake4, and both versions
of vdrift with 2.6.37 kernel and current mesa master. No sign of this bug.
Closing.

BTW the doom3 segfault (either complains about vertex array in virtual memory
or cannot open libGL.so) is solved by removing the libgcc_s.so.1 and
libstdc++.so.5 from its directory. The same applies to quake4.

Yeah, that's because doom3/quake4 and your system's libGL link to incompatible
libgcc_s.so.1 and libstdc++.so.5.

Yeah, I knew the reason immediately after removed those. Furthermore, the faq
on zerowing.idsoftware.com says:
Should I replace libgcc and libstdc++ with the ones from my distro?
While we haven't seen that replacing them will noticeably improve performance,
on some distribution (gentoo for instance) this is known to cause crashes. At
your own risks.

Now _not_ replacing them causes crash. Maybe this should be mentioned on
http://www.x.org/wiki/RadeonProgram.
Who can edit that page anyways? It seems quite outdated.

Anyone I guess. All you need to do is to create an account.
