rv200 + DRI -> insta-hang (vbs not dirtied)

[Tim Hull]

I have an IBM ThinkPad T42 with an integrated ATI Mobility Radeon 7500 video
card. I recently tried
out the new Hoary Array 3.5 live CD, and while I was booted from it decided to
try running glxgears to see how
many fps I could get. However, after running glxgears, the system hung solid
except for the mouse pointer -
I had to power cycle the system (I couldn't even use ctrl-alt-del or the like).

Reported, fix pulled from Mesa a few days ago.

 xorg (6.8.1-1ubuntu12) hoary; urgency=low
 .
   * Resync Imakefiles for Mesa, so t_vb_cull gets built, and i915_dri is
     loadable (closes: Ubuntu#5664).
   * Also from Mesa 6.2.x branch, grab fix for lockups on Radeon M7-class chips
     (fd.o#2361).
   * Update from 6.8 branch; remove patches #096 and #601 as they were merged in
     this morning. This release is almost entirely equivalent to 6.8.1.903
     (aka 6.8.2RC3).
   * Disable building of largely defunct XRX plugin in linux.cf.
   * Guess at a reasonable default for $DISPLAY_TYPE if xresprobe doesn't feed
     us a display type (closes: Ubuntu#5639).
   * Set $LAPTOP in xserver-xorg.postinst.in.
   * Move the test for resolutions-via-DDC-but-no-sync-ranges around in
     xserver-xorg.postinst.in, so $NRES is set when we call it (closes:
     Ubuntu#5754).
   * Write sync ranges for all r128s on powerpc (closes: Ubuntu#5940).
   * Remove speedo and v4l from the list of modules loaded per default.
   * Fix comments at the top of the config file to be more accurate (closes:
     Ubuntu#5748).
   * Don't load GLcore in the default set of modules, per Adam Jackson.
   * Add hardened Linux support via a small call in postinst.
   * Change default builder from canonical.com -> ubuntu.com.
   * Add <X11/Xlib.h> to scrnsaver.h's #includes, add libx11-dev dep to
     libxss-dev.
