I also tried loading drm with debug=1 the other day. Here is the result.

Please leave it as needs info. This is one way to keep track of bugs that are being triaged. can you attach the output of lspci. also is this an onboard video card or a card you added?

Confirmed. Interesting, since this is happening to me on PCI-E X800 card, and you have a card from a totally different series. I have failed a bug about this upstream: https://bugs.freedesktop.org/show_bug.cgi?id=7697

For me changing r300_cmdbuf.c "solves" the problem (ie. does not do checking anymore, which it for some reason fails in doing but works when bypassed), but that file should not even be used in your case, so it might or might not be a bug that is similar.

If you want to dwell into the problem, I'd suggest trying to find where in the kernel radeon drm driver the error happens. See linux-core and shared-core -directories in http://gitweb.freedesktop.org/?p=mesa/drm.git;a=summary , compilable with "make" inside the linux-core directory - then copy drm.ko and radeon.ko to /lib/modules/.../kernel/drivers/char/drm -directory and either reboot or shutdown X (/etc/init.d/gdm stop) and rmmod radeon && rmmod drm && modprobe radeon.

Your specific case should be fixed in Linux kernel 2.6.19, which is included in Ubuntu 7.04, according to another (fixed) bug report https://bugs.freedesktop.org/show_bug.cgi?id=7595

If you want, you may check the fact using the new _non-final_ snapshot of Ubuntu 7.04 development, "Herd 1" at http://cdimage.ubuntu.com/releases/feisty/herd-1/

I installed feisty, and direct rendering did indeed work. I am now a happy Beryl user :) . Thanks to everybody involved in fixing this bug.

Good to hear. As of today, also the similar bug with my X800 got fixed in Mesa DRM's development tree. Not in Ubuntu yet, but I'd guess it has chances to get in kernel 2.6.20 which will be in feisty final. Anyway, this bug report was about your R200-related problem.

Confirming that 2.6.20-rc2 includes the fix also for Radeon 9500 - X850.
