[ubuntu-x] nvidia crash running 3dmark2000 in Ubuntu 10.04

[Dan Kegel]

Hi folks,
I just started benchmarking wine with 3dmark2000, 3dmark2001, and 3dmark06,
and have noticed crashes in the 195.xxx nvidia drivers
on both Gentoo and Ubuntu 10.04.

Here's an example backtrace on Ubuntu 10.04 with the nvidia 195.36.15 drivers
(sorry, I haven't reproduced it since I installed debugging symbols)
0: /usr/bin/X (xorg_backtrace+0x3b) [0x80e937b]
1: /usr/bin/X (0x8048000+0x61c7d) [0x80a9c7d]
2: (vdso) (__kernel_rt_sigreturn+0x0) [0xb781b410]
3: /usr/bin/X (0x8048000+0x144488) [0x818c488]
4: /usr/lib/xorg/extra-modules/nvidia_drv.so (0xb560d000+0x31db67) [0xb592ab67]
Segmentation fault at address 0x3c3b47
Caught signal 11 (Segmentation fault). Server aborting
This one happened when I pressed escape about two seconds into
the 3dmark2000 run.   I had two crashes this morning, still trying to
get a log with more information.

The Gentoo crash happened while running 3dmark2006.

In case anyone wants to repeat exactly what I'm doing, the procedure is
to install wine (and cabextract) and do
  svn checkout http://winezeug.googlecode.com/svn/trunk/ winezeug
  cd winezeug
  sh yagmarktest

That will loop forever running 3dmark2000, 3dmark2001, and 3dmark2006
(um, though 3dmark2006 requires a tiny patch to wine, so if you don't
want to build wine, you'll need to remove that from yagmarktest, it's
an easy edit).
