I did dome more testing with different cards an got a surprise. The machine works fine with other AGP cards - one MX440 with nouvea, another RV100 QY and a R200. They do have interrupt in lspci -vvv output. Why does this specific card not have its IRQ routed - card ROM problem? -- Meelis Roos (mr...@linux.ee) _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel
