            Bug ID: 60555
          Assignee: dri-devel at lists.freedesktop.org
           Summary: [r300g] RADEON_NO_TCL=1 hardlock
          Severity: trivial
    Classification: Unclassified
                OS: All
          Reporter: pavel.ondracka at email.cz
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/DRI/r300
           Product: Mesa

This is not really a bug as normal user will never encounter this, just some
nuisance I discovered when I tried to investigate bug 60552 a little bit.

When RADEON_NO_TCL=1 is used (which is useful in diagnosing compiler bugs), the
whole machine sometimes hardlocks. App from bug 60552 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.
