           Summary: Radeon DRI, suspend to disk, resume -> system hangs
           Product: xorg
           Version: 7.2
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW

When resuming after suspend to disk with activated dri extention on Radeon
cards (R100 chips) system hangs (screen is black, system doesn't respond).
Without dri extention suspend to disk and resume works OK. 

Tested on hardware: Mobile Radeon 7000, Radeon 7200 cards. 
Tested on software: Xorg: 7.1, 7.2, Linux distributions: Kubuntu, Mandriva,
kernels: 2.6.17 (distribution), 2.6.20(distribution), 2.6.21(vanilla), "suspend
systems": swsusp(part of linux kernel), swsusp2

How to reproduce:
1) System with Radeon R100 card with running Xorg with dri extention
2) Suspend to disk
3) Start resumming
