Sorry if I write into the wrong list, but I found some similar
messages here. I have a system based on Debian Lenny with X.org
1:7.3+18 and VIA CX700 video chip. When I run glxgears it gives
$ DISPLAY=:0 glxgears
do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try running with LIBGL_THROTTLE_REFRESH and LIBL_SYNC_REFRESH unset.
It seems to work fine, giving about 500 FPS, but after some time X
server and the whole system simply hanged up.
Mesa is 7.0.3 (with patches from chip vendor), kernel 2.6.26
DISPLAY=:0 glxheads :0
GL_VERSION: 1.2 Mesa 7.0.3
GL_VENDOR: VIA Technology
GL_RENDERER: Mesa DRI UniChrome 20060710 x86/MMX/SSE2
Any ideas how to fix it?
