Looks as though it's time to stop buying ATI products. I've been using ATI cards since they made the VGA Integra. If they can't expend the minimal effort to fix Linux drivers for relatively recent products, they don't want my business. This message suggest my problem is a known issue. http://www.ussg.iu.edu/hypermail/linux/kernel/0409.1/0359.html Re: [BUG] r200 dri driver deadlocks From: Alexander E.

And drum roll please... Too early :( The dri cvs snapshot works fine on both it's own kernel module, and the one that comes with 2.6.8.1. So now what? (And does this mean it isn't a kernel bug?) I have compiled both the kernel module and the replacement X server from the yesterday's CVS checkout of DRI (but according to "outdated" instructions in the Wiki). It made a difference against XFree86 4.4.0 + in-kernel radeon.ko. The difference is that, instead of just hanging, after several minutes of run time applications (e.g. "really slick screensavers") print: drmRadeonIrqWait: -16 and exit with status 1. After that, 2D works, but the _next_ fullscreen OpenGL application hangs the system immediately on start. -- Alexander E. Patrakov -- Regards, Steven
