suspend to disk -> resume -> X with DRI extension on R100 chips hangs

From: Radim Luža
Date: Wed Oct 25 2006 - 03:47:27 EST

Good morning

I noticed following problem:
After resuming from suspend to disk Xorg with DRI switched on hangs. System is not affected by Xorg hang. If I login via SSH I can kill X server and start it again - with same result. X server hangs even after I suspend from text mode with X not running and with unloaded modules radeon and drm and resume then and try to start X server. With DRI switched off in xorg.conf X resumes correctly.

Info about my system:
