           Summary: Xorg lockup using Radeon Xpress 200 (RS480)
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: bugzilla at hbar.cc
         QAContact: xorg-team at lists.x.org


After running for a few minutes (amount of time varies, sometimes 5 minutes
after login, sometimes an hour), X freezes and becomes unresponsive. Often the
mouse pointer still responds to movement but cannot select anything. It is
possible to SSH in from a remote machine and see that Xorg is using 100% CPU.

I am not a coder but I will give you all the help I can in resolving this,
because this machine is currently unusable.  I submitted this bug originally to
Ubuntu's lanchpad, and all of the relevant hardware information is attached
there:
