Unable to reserve mem region

I have a VIA Unichrome video card intergrated in the K8N800 chipset. I installed a drm module and a via module under that. Downloaded from http://dri.freedesktop.org/

The modules loaded successfully but here is an error I got in syslog:

Code:

PCI: Unable to reserve mem region #1:4000000@f0000000 for device 0000:01:00.0

Here is the card from lspci:

Code:

01:00.0 VGA compatible controller: VIA Technologies, Inc.: Unknown device 3108 (rev 01)

What is the problem? And how to fix it?

MezzyMeat,

This is just a wild guess, but I thinik ( and I stress the word 'think' ), that when you
lspci and you get a " Unknown device xxxx ", (xxxx = device number) it means that
the kernel does not support the device.

You may need to find a kernel patch for the device, OR upgrade the kernel maybe?
What kernel are you running? IF slack 10.0 (under your name), you still have the
2.4.xx kernel?

You are right, I get that with lspci

Code:

01:00.0 VGA compatible controller: VIA Technologies, Inc.: Unknown device 3108 (rev 01)

I have upgraded my kernel to 2.6.11.5 and I there are no support for the chipset by default. BUT, I have compiled two modules (drm and via). Drm was already in the kernel but under drm there was no via, so I replaced them both as a how-to said I should do. Both modules load fine, I modprobe via and then both via and drm are loaded. Here is what that action leaves in dmesg:

Code:

[drm] Initialized drm 1.0.0 20040925

PCI: Unable to reserve mem region #1:4000000@f0000000 for device 0000:01:00.0
