           Summary: [bisected] KDE KWin crashes on start with delayed BO
                    mapping
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: jlp.bugs at gmail.com


After updating the mesa today KWin started to crash/segfault on start. I've
bisected and the first commmit that causes the crash is:
5e15497452cf3e4d2fc76fdc6ed8113d0891b467
r600g: delay mapping until first map request. (v2)

This is with KDE KWin 4.6.3 and on a laptop with integrated ATI Mobility Radeon
HD 5470.

Later I've also tried with glxgears, which appears to work fine if in window
and crashes if started with -fullscreen option.
