Hi, I have been tracking a DRI crash-on-startup bug with the Xorg server at: * https://bugs.freedesktop.org/show_bug.cgi?id=16200 The bug was originally testing on the xf86-video-ati driver. I recently pulled down the quick-and-dirty-2d branch of radeonhd and tried running Xorg with EXA+DRI, and got a similar server busy-loop at startup. I did some more testing, and also I still don't get and DRI rendering from the card in the Accel-disabled mode. The recent changes to remove some hard-locks from the driver (by glisse@) have the drm kmod now producing the following info message, in an infinite loop: info: [drm] wait for fifo failed status : 0x9001C100 0x00080000 Before these changes went in, I was able to get intermittent success using EXA+DRI with the xf86-video-ati driver. However, lately, I cannot get the server to start anymore. Using the radeonhd driver, I was able to get it to start with DRI when I turned acceleration off, but the DRI windows just remain black, with no output. I get those info: messages listed above dumped to the console in this case too, as well as when I run radeonhd with EXA+DRI and the xserver locks up (busy-loops) on startup. Curious if you have any instructions in particular that I can look at regarding this. I am suspicious of, perhaps, EXA and DRI stepping on each other, but I don't really know. Maybe someone else can take a look and get a better idea... In all cases I can SSH to the laptop, and reboot it from the shell.
