[Radeon RV280] radeon_cs_gem.c:181: cs_gem_write_reloc: Assertion »boi->space_accounted« failed, core dumped

[Jochen Rollwagen]

I've recently ported the peopsxgl OpenGL-GPU-Plugin for the pcsx 
Playstation1 Emulator to the Powerpc-architecture. When running certain 
games (for instance "Vagrant Stories") during longer cut-scenes i get a 
reproducible crash of the radeon drm driver (i.e. it always crashes at 
certain points in the scene) with the following message (in german):

pcsx: radeon_cs_gem.c:181: cs_gem_write_reloc: Zusicherung 
»boi->space_accounted« nicht erfüllt.
Abgebrochen (Speicherabzug geschrieben)

This happens with all the latest 3.10, 3.12 and 3.14 kernels.

Other than that i'm running the latest xorg-ati driver, libdrm and mesa 
from git on a Mac Mini G4 (PowerPC).

OpenGL vendor string: Mesa Project
OpenGL renderer string: Mesa DRI R200 (RV280 5962)  TCL DRI2
OpenGL version string: 1.3 Mesa 10.1.6 (git-42f86ef)

I guess the issue is memory/vm/swap-related since the machine only has 1 
gb RAM. The GPU has 64 MB VRAM.

Any ideas what i could do to avoid these crashes ?
