I've already tried to bisect this crash, but can't find the first "good" commit. I suspect that I was running Fedora 12 instead of Fedora 13 when it worked last time. WoW now crashes shortly after logging in; here is the backtrace: Backtrace: =>0 0x00005d31 (0x0039f010) 1 0x7dc1f44d radeon_drm_bufmgr_set_tiling+0xbc() in r300_dri.so (0x0039f010) 2 0x7dc2e272 r300_flush_cb+0x21() in r300_dri.so (0x0039f040) 3 0x7dc1f44d radeon_drm_bufmgr_set_tiling+0xbc() in r300_dri.so (0x0039f040) 4 0x7d61f040 (0x0039f060) 5 0x7dc37e39 r300_set_framebuffer_state+0x148() in r300_dri.so (0x0039f060) 6 0x7dc1ebd2 radeon_r300_winsys_buffer_set_tiling+0x31() in r300_dri.so (0x0039f0c0) 7 0x7dc37e39 r300_set_framebuffer_state+0x148() in r300_dri.so (0x0039f220) 8 0x7ddacb32 util_blitter_copy_region+0x531() in r300_dri.so (0x0039f220) 9 0x7d5acc38 (0x0039f290) 10 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 11 0x0039f1a0 (0x0039f290) 12 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 13 0x0039f204 (0x0039f290) 14 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 15 0x00000001 (0x0039f290) 16 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 17 0x00000000 (0x0039f290) 18 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 19 0x00000002 (0x0039f290) 20 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 21 0x0039f120 (0x0039f290) 22 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 23 0x0039f160 (0x0039f290) 24 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 25 0xc0086464 (0x0039f290) 26 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 27 0xb74d31f9 (0x0039f290) 28 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 29 0x7e8150f8 (0x0039f290) 30 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 31 0x7e80da7e (0x0039f290) 32 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 33 0x0000000d (0x0039f290) 34 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 35 0xc0086464 (0x0039f290) 36 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 37 0x0039f160 (0x0039f290) 38 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 39 0x7de4a174 _DYNAMIC+0x72f() in r300_dri.so (0x0039f290) 40 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 41 0x60000004 (0x0039f290) 42 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 43 0x0039f270 (0x0039f290) 44 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 45 0x7e80da5b (0x0039f290) 46 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 47 0x7d2eb470 (0x0039f290) 48 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 49 0x7d2c8e60 (0x0039f290) 50 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 51 0x0039f160 (0x0039f290) 52 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 53 0x00000002 (0x0039f290) 54 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 55 0x7d20c308 (0x0039f290) 56 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 57 0x0000000d (0x0039f290) 58 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f220) 59 0x7dc2bf01 r300_get_swizzle_combined+0x10() in r300_dri.so (0x0039f290) 60 0x7dc409eb r300_resource_copy_region+0xea() in r300_dri.so (0x0039f2f0) 61 0x7dc2d9e5 r300_texture_transfer_destroy+0xf4() in r300_dri.so (0x0039f2f0) 62 0x7d5acc38 (0x0039f310) 63 0x7dd29005 st_texture_image_unmap+0x34() in r300_dri.so (0x0039f310) 64 0x7ddd1cdb u_transfer_destroy_vtbl+0x1a() in r300_dri.so (0x0039f330) 65 0x7dd29005 st_texture_image_unmap+0x34() in r300_dri.so (0x0039f410) 66 0x7dd66554 st_TexImage+0x3b3() in r300_dri.so (0x0039f460) 67 0x7dd66b6e st_TexImage2D+0x7d() in r300_dri.so (0x0039f4e0) 68 0x7dccba3a _mesa_TexImage2D+0x229() in r300_dri.so (0x0039f540) 69 0x7ea6eebe wine_glTexImage2D+0xcd() in opengl32 (0x0039f5a8) 70 0x0065e748 in wow (+0x25e747) (0x0039f600)
I'm not a developer, but you may try recompiling mesa and wine with CFLAGS="-g -gdwarf-2", you will get a better backtrace.
Created attachment 36584 [details] Recent backtrace using mesa git with -gdwarf-2
In src/gallium/drivers/r300/r300_context.c static void r300_flush_cb(void *data) { struct r300_context* const cs_context_copy = data; cs_context_copy->context.flush(&cs_context_copy->context, 0, NULL); } The crash happens when the context.flush function pointer does not contain a valid value.
I believe the "data" pointer is not valid. I have committed some fixes, can you please test latest mesa git?

(In reply to comment #4) > I believe the "data" pointer is not valid. Or possibly the context.flush field has not been assigned? I am having curious success with this simple patch: --- a/src/gallium/drivers/r300/r300_context.c +++ b/src/gallium/drivers/r300/r300_context.c @@ -125,7 +125,9 @@ static void r300_flush_cb(void *data) { struct r300_context* const cs_context_copy = data; - cs_context_copy->context.flush(&cs_context_copy->context, 0, NULL); + if (cs_context_copy->context.flush) { + cs_context_copy->context.flush(&cs_context_copy->context, 0, NULL); + } } #define R300_INIT_ATOM(atomname, atomsize) \
(In reply to comment #4) > I believe the "data" pointer is not valid. That data pointer looks like it *used* to belong to a r300_context object that has since been destroyed. Basically, r300_create_context() stores a reference to the newly-created r300_context object inside the radeon_libdrm_winsys struct: rws->set_flush_cb(r300->rws, r300_flush_cb, r300); Warcraft then destroys the context again, but this reference inside the winsys lingers somehow. And then Azeroth explodes when radeon_drm_bufmgr_set_tiling() tries to flush the buffer data.
I think you are right. That seems to be the only logical explanation. The fix is not trivial, I'll send you a patch when I have one.
OK so I've committed some fixes because they don't break anything. Please let me know if they help. PS: There is a new bug in the GLSL compiler in master. I hope you won't hit that.
(In reply to comment #9) > OK so I've committed some fixes because they don't break anything. Please let > me know if they help. Yes, that seems to have fixed it. Thanks.
