           Summary: Regression in 7.6.1, glxgears locks the machine (rv280)
           Product: Mesa
           Version: 7.6
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r200
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: zarniwhoop73@googlemail.com


Building a fresh system, xorg-7.5, in particular xorg-server-1.7.4 (built
without dbus or hal), xf86-video-ati-6.12.4. xf86-input-evdev-2.3.2, gcc-4.4.2,
linux kernel 2.6.32.2.

 I was running some of my later buildscripts, after I'd got xscreensaver
installed, and twice I left it running and returned to a blank screen and only
MagicSysRQ functioning.  Nothing in the logs.

 Did some testing, established that glxinfo reported
direct rendering: yes
 then attempted to run glxgears.  The small application window appeared, with a
black background, but no gears, and from that point only MagicSysRQ worked.
This was repeatable.

 I've now ripped out 7.6.1 and built 7.6 (and rebuilt the server against the
7.6 headers), and it works fine - no problem with glxgears, left the
screensaver running for 30 minutes without any sign of a problem.

 This is an old RV280 [Radeon 9200 SE].
