Bug#740097: nVidia driver 304.121 does NOT solve issues

[Benjamin Krause]

My configuration is nearly identical to those mentioned above:

`# uname -a
Linux obx-056-ws 3.13-1-amd64 #1 SMP Debian 3.13.5-1 (2014-03-04) x86_64
GNU/Linux`

`# lspci | grep VGA
02:00.0 VGA compatible controller: NVIDIA Corporation G71 [GeForce 7900
GT/GTO] (rev a1)`

There no 'nvidia' packages listed in dpkg.

I received the 'acpi_os_wait...." in logs.

Problem began immediately upon 'apt-get dist-upgrade' to 3.13-1-amd64.

I installed that last proprietary drive from nVidia
'NVIDIA-Linux-x86_64-304.121.run' which I downloaded directly form them.  I
was unable to get it to install using DKMS so had to install without.
 Otherwise installation went without event.

It now boots directly into KDE desktop without issue, flashing the nVidia
splash screen.  It seems to be working normally until I push it a little
with OpenGL.  After running for about a minute or so while requiring OpenGL
(not sure if its OpenGL or just because of heavy rendering load) it starts
to lag fast, until within a few seconds it's no longer usable.  After
waiting a few minutes for the close application instructions to be
executed, it then goes back appearing normal again.  This effect is also
seen when requesting full screen video, another heavy rendering task.

This behavior is identical to what I received when I previously installed
304.117 with the section in nv_acpi.c commented out and tested it.  This
makes me wonder if nVidia just released the same driver with this patch in
it...  possibly not addressing the problem adequately.
