This seems to mitigate a crash in glxgears when I resize the window

(frontbuffer rendering, so the frontbuffer doesn't change). Problem
not fully solved, though: After a while of constantly resizing the
window the kernel cs checker complains:
[drm:r100_cs_track_check] *ERROR* [drm] Buffer too small for z
buffer (need 1302400 have 1257472) !
[drm:r100_cs_track_check] *ERROR* [drm] zbuffer (592 4 0 550)
[drm:radeon_cs_ioctl] *ERROR* Invalid command stream !
So this is probably just a gross hack. Comments from people with
more clue than me higly welcome ;)
This is a pure hunch, but can you check if this helps:
Edit radeon_prepare_render() in radeon_common_context.c to uncomment
the commented out statement...
radeon_draw_buffer(radeon->glCtx, &(drawable->driverPrivate)->base);
in this comment:
/* Intel driver does the equivalent of this, no clue if it
is needed:
* radeon_draw_buffer(radeon->glCtx, &(drawable-
>driverPrivate)->base);
*/
I was the guy who wrote that patch and had no clue if it is needed.
Maybe this bug provides an answer?
thanks,

Patch not tested on anything else than my rv270. Oh, and this is
on a Mac Mini G4 ppc machine.
Yours, Daniel
