Just recently I updated to Mesa from git master and since I've updated I got some strange crash while using the menus in programs. X often crashed when I use the menus. I can reproduce this crash if I click on a menu like File so that a submenu shows up and then I move the mouse pointer to next menu like Edit so that the previous submenu closes and the new one opens. So if I move the mouse over the menu entries sooner or later X will just crash and exit. i've tried looking in X log file and in dmesg and I couldn't find anything there. What I could find was in /var/log/kdm.log: *********************************WARN_ONCE********************************* File radeon_dma.c function radeonReleaseDmaRegions line 348 Leaking dma buffer object! *************************************************************************** X: radeon_bo_legacy.c:207: legacy_is_pending: Assertion `bo_legacy->is_pending <= bo->cref' failed. This is on HP Compaq nx6325 with this integrated radeon graphics. 01:05.0 VGA compatible controller: ATI Technologies Inc RS482 [Radeon Xpress 200M] I'm using KDE 4.3.1 and you have to have desktop effects enabled to trigger the crash.

Same problem with HP Compaq nc6400 containing: 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc M52 [Mobility Radeon X1300] [1002:714a] I have bisected on 7.6 branch.

Any ideas Pauli?
Same problem here on Mobility x1400 with latest packages from the openSuse Xorg:X11 repository. Happens for me only when KDE 4 desktop-effects are enabled, though. If I disable them, I can work as usual. Enabling them leads to X crashing within a couple of seconds. Couldn't find the error message in Xorg.0.log but kdm.log catched it as well.
Does anyone know a way of reproducing this other than installing KDE?
On my radeon x1200 (rs690) the desktop loads but when opening any application window (for example system settings) Xorg crashes and I'm back at kdm login. From this point on changing to terminal ctrl+alt+f1 doesn't work as by doing that I'm left with kdm bitmap and some graphical garbage is produced at the top of the screen. When compositing is disabled everything is ok, also strangely when booting up the kernel with radeon.modeset=1 and using KMS compositing in kde works as it should and the bug is gone.
I confirmed the crash on RV515 on 32-bit by installing kwin and that reverting the commit fixes it.

FYI, this bug is screwing many KDE 4 users using their desktop environment with OpenGL effects (enabled by default) on radeon cards. The bug triggers semi-random X session crashes and people lose data and otherwise get annoyed. Moreover, this is a regression from meta 7.5. The origin of the crashes is not very obvious without deep investigation which a typical user is unable to do. Please consider this problem of higher priority.
As Pauli seems to be MIA, any better ideas than just reverting the bisected commit?

I wonder if reverting that commit brought all the "radeon_dma.c:210: radeonRefillCurrentDmaRegion: Assertion `dma_bo->bo->cref == 1' failed" reported in https://launchpad.net/bugs/459961 though.
