           Summary: Radeon 9200 hang on multimedia device init
           Product: xorg
           Version: CVS_head
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: dark at mama.indstate.edu


The X server hangs whenever it attempts to initialize any of the drivers in the
multimedia directory.  Server can still be kill -9'ed without machine death, and
can be worked around by removing lib/modules/multimedia.  Minor efforts at
tracking this down showed it to be hanging in RADEONI2CWriteRead() routine in 
xc/programs/Xserver/hw/xfree86/drivers/ati/radeon_mm_i2c.c while waiting for
I2C_GO to clear in the read loop.  Note that changing to R200_I2CWriteRead()
does not affect the behavior.
