Description jfr 2006-02-14 09:34:45 UTC

Overview:
dmesg reports "Unable to reserve mem region" for ATI Rage 128 Pro. OpenGL Apps 
crash or freeze.

To Reproduce:
1) modprobe r128
2) startx
3) Start one of various OpenGL apps

Actual Results (all reproducible everytime):
1) Module loads, but dmesg reports error - see below.
2) Works.
3) App crashes (example a) or freezes (b) or works (c)
   a) game gltron: exits on selection of new game, output: Rage 128 timed out...
   b) game Privateer Gemini Gold: Whole system freezes
   c) glxgears: runs with ~1000fps

Expected Results:
3a,b) should run, as it does without DRI.

My Software:
Linux Mandriva 2006
kernel 2.6.11
xorg 6.9.0
DRI snapshot 06-Feb-2006

My Hardware:
PC, ATI Rage 128 Pro AGP 4x

I can also confirm this bug on a Dell Inspiron 8000 with an ATI Mobility M4 8mb
card. The relevent dmesg output:

There are several problems with the r128 driver on my laptop. I suspect that
some of these freezes are related to a CCE idle timeout bug, see
https://bugs.freedesktop.org/show_bug.cgi?id=1889 - I have recently added a
patch I found that may hopefully alleviate some system freezes.

Is there a framebuffer driver loaded on the system? vesafb or atyfb?

Does it work with the kernel DRM? don't install the modules from the DRI snapshot..

No.

snapshot..

I'll get on that as soon as I have access to the system again.
