2.6.38 Nvidia Problems : NVRM: The system BIOS may have misconfigured your GPU.

[Venkatram Tummala]

Hi,

I am trying to run 2.6.38(x86_64) with nvidia 7200GS video card with 4GB of
RAM. Although the kernel boots up, i just get a blank screen. I can ssh into
the system. dmesg shows the following output :

[   11.535703] NVRM: This PCI I/O region assigned to your NVIDIA device is
invalid:
[   11.535704] NVRM: BAR1 is 0M @ 0x0 (PCI:0000:01:00.0)
[   11.535706] NVRM: The system BIOS may have misconfigured your GPU.

It seems lots of people had the same issues with some older kernels (
2.6.27) and this apparently happens only with 4GB of RAM with nvidia.
Anything less than 4GB of RAM is not a problem.

Has anyone figured this out yet.
