        <pre>This is not really a bug as normal user will never encounter this, just some
nuisance I discovered when I tried to investigate <a class="bz_bug_link 
          bz_status_NEW "
   title="NEW --- - [r300g] Carvisualizer webgl demo: black flickering spots over the car"
   href="show_bug.cgi?id=60552">bug 60552</a> a little bit.

When RADEON_NO_TCL=1 is used (which is useful in diagnosing compiler bugs), the
whole machine sometimes hardlocks. App from <a class="bz_bug_link 
          bz_status_NEW "
   title="NEW --- - [r300g] Carvisualizer webgl demo: black flickering spots over the car"
   href="show_bug.cgi?id=60552">bug 60552</a> is a good way to
reproduce this.

This debug option should be either fixed, or if it no longer considered useful,
then it should be removed. 

BTW this was working not a year ago, so I can probably run a bisect if needed.</pre>
