4 holds heavyweight lock

[Margaret Doll]

What does "[drm:radeon_lock_take] *ERROR* 4 holds heavyweight lock" 
mean?

When I start up a Tecplot  10.0.3 session  on a Dell station  running  
2.4.20-30.9, the screen freezes up.

/var/log/messages contains:

  Resolved address "xml:readonly:/etc/gconf/gconf.xml.mandatory" to a 
read-only config source at position 0

We haven't had problems with various versions of Tecplot on Dell 
stations running various versions of RedHat.
