Hi I get random crashes with the radeon driver. Fedora 9, with kde4 and a ati FireGlt2 (9600) card (recently updated from FC8). tail of Xorg.0.log: (II) RADEON(0): Adding Screen mode: 640x480 (II) RADEON(0): Total number of valid Screen mode(s) added: 7 (II) RADEON(0): Output: S-video, Detected Monitor Type: 0 FreeType: couldn't open face /usr/share/X11/fonts/Type1/cour.pfa: 1 FreeType: couldn't open face /usr/share/X11/fonts/Type1/cour.pfa: 1 FreeType: couldn't open face /usr/share/X11/fonts/Type1/cour.pfa: 1 Backtrace: 0: /usr/bin/Xorg(xf86SigHandler+0x79) [0x80bc549] 1: [0x110400] 2: /usr/lib/dri/r300_dri.so(r300DestroyTexObj+0x69) [0x5c17e9] 3: /usr/lib/dri/r300_dri.so(driDestroyTextureObject+0x55) [0x5ac7c7] 4: /usr/lib/dri/r300_dri.so [0x5c33f9] 5: /usr/lib/dri/libdricore.so [0xd89b11] 6: /usr/lib/dri/libdricore.so(_mesa_HashDeleteAll+0x48) [0xdbc97a] 7: /usr/lib/dri/libdricore.so [0xd8a10d] 8: /usr/lib/dri/libdricore.so(_mesa_free_context_data+0x19f) [0xd8aad2] 9: /usr/lib/dri/libdricore.so(_mesa_destroy_context+0x20) [0xd8ab27] 10: /usr/lib/dri/r300_dri.so(radeonCleanupContext+0x1d) [0x5b1bd6] 11: /usr/lib/dri/r300_dri.so(r300DestroyContext+0x3c5) [0x5b6ed9] 12: /usr/lib/dri/r300_dri.so [0x5b088c] 13: /usr/lib/dri/r300_dri.so [0x5ad5ee] 14: /usr/lib/xorg/modules/extensions//libglx.so [0x1b7559] 15: /usr/lib/xorg/modules/extensions//libglx.so(__glXFreeContext+0x89) [0x1ac3e9] 16: /usr/lib/xorg/modules/extensions//libglx.so [0x1ac437] 17: /usr/bin/Xorg(FreeClientResources+0xe6) [0x806dab6] 18: /usr/bin/Xorg(CloseDownClient+0x6f) [0x807fddf] 19: /usr/bin/Xorg(Dispatch+0x1e0) [0x8085c40] 20: /usr/bin/Xorg(main+0x47d) [0x806b63d] 21: /lib/libc.so.6(__libc_start_main+0xe6) [0x3cc5d6] 22: /usr/bin/Xorg(FontFileCompleteXLFD+0x22d) [0x806aa21] How to debug further?
> I get random crashes with the radeon driver. The backtrace you pasted indicates the crash happened when cleaning up GLX resources for an indirect rendering context. Unless you're intentionally running 3D apps with indirect rendering, this could indicate a configuration problem preventing direct rendering, or that kwin crashed. > How to debug further? A more useful backtrace could be obtained with gdb (making sure debugging symbols are available).
I have been able to pinpoint this a bit further. I can reliably crash X11 (both under gnome and KDE) using Mathematica 6.0. I do a Plot3D (which calls 3d rendering), and then quit the application. This crashes X11. Interestingly, it only happens in XAA but not in EXA mode.
Can you reproduce it with newest mesa and xf86-video-ati?
