           Summary: PCI config space register access unprotected
           Product: xorg
           Version: CVS_head
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DDX/xorg
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: kem at freedesktop.org


The int10 module directly accesses PCI config space via the 0xCF8 and 0xCFC
registers.  This causes system lockups on multiprocessor systems when multiple
processes are trying to access PCI config space.
