Created attachment 78729 [details] dmesg With my A10-5700 ARUBA I have a problem running 32bit applications under 64bit kernel (not tried 32bit kernel) while 64bit applications are fine. Essentially the X server crashes with a segfault after the following messages; radeon 0000:00:01.0: bo ffff88022f44b000 va 0x00000000 conflict with (bo ffff88022ee16c00 0x01F00000 0x026F8000) radeon 0000:00:01.0: bo ffff88022f44b000 don't has a mapping in vm ffff880224c97e00 radeon 0000:00:01.0: bo ffff88022f449000 va 0x00000000 conflict with (bo ffff88022ee16c00 0x01F00000 0x026F8000) radeon 0000:00:01.0: bo ffff88022f449000 don't has a mapping in vm ffff880224c97e00 radeon 0000:00:01.0: bo ffff88022ee16000 don't has a mapping in vm ffff880224c97e00 radeon 0000:00:01.0: bo ffff88022ee16400 don't has a mapping in vm ffff880224c97e00 [...REPEAT...] radeon 0000:00:01.0: bo ffff88023527c000 don't has a mapping in vm ffff880224c97e00 [CRASH] System is running; - Linux 3.9.0 with all radeon patches from drm-next-3.10-2 (but problem occurrs with standard Linux 3.8 and 3.9 too, though unknown for earlier kernels) - Current Mesa git head for both 64 and 32 bit (definitely no old libraries).

FWIW, it looks like the crash happens in a GLX indirect rendering path. Unless you're intentionally using indirect rendering, I suspect there's a problem with your 32-bit Mesa setup, causing the 32-bit apps to fall back to indirect rendering.
Sorry, appears the build system (not Mesa's) had started stripping the "--with-dri-searchpath" I'd set. Now resolved.
