As the subject says, I'm wondering if anyone out there has experienced hangs on logging out from xdm (or perhaps switching VTs) with Radeon or matrox (perhaps r128, too) cards using the updated DRM in -current and XFree86 4.3.0. If so, I may have a fix, but I'm wondering if this affects FreeBSD.
Yes, I had them from 5.0 onwards until -p7. Not only with radeon but
also (although not so often) with mga. They don't seem to happen anymore with the Matrox card in -p7 but I can't right now check if it's still problematic with a Radeon (I have swapped cards in hope to workaround that problem.) But since I also had problems with the mga before -p7 and they don't seem to exist anymore now perhaps the problem has gone away? (The problem manifested itself in the X server taking 100% cpu in kernel mode, and trying to kill it, or trying to reboot made the machine freeze solid. It only happened when the X session was terminated / X server was restarted, and occasionally in some xscreensaver hacks, after a while, although I couldn't ascertain this because I usually am not there when xscreensaver is running... ;)
