Hi, I experience a crash in the nouveau part of the mesa driver:
src/gallium/drivers/nouveau/nv30/nv30_vbo.c in function: void nv30_vbo_validate(struct nv30_context *nv30) Sometimes, ve->vertex_buffer_index seems to be greater or equal nv30->num_vtxbuf. If this happens, PUSH_RESRC crashes! How can this happen?? I tried to break out of the for-loop for (i = 0; i < vertex->num_elements; i++) when the problem appears. If I do this, the driver won't crash anymore, but some screen elements are missing. A short while later I get a GPU lockup message: > kernel: nouveau E[ DRM] GPU lockup - switching to software fbcon I can reproduce this crash with a Qt5.3 Quick2 application. Where would be the next point to look into this? Can anyone help me with this? Does a mmiotrace help? My system: - Board: ASRock N68C-GS FX with NV68 GeForce 7025 OnBoard - Linux 3.18.4, (32 bit) - Mesa-10.4.4 - Regards, Arno
