--- Comment #1 from Marek Olšák maraeo@gmail.com 2010-06-09 16:37:54 PDT --- I don't have this problem.
I have reviewed all the r300-related commits between your good and bad ones. One of these commits must be the cause:
ebe2b54 r300g: report vertex format support in is_format_supported 3262554 r300g/swtcl: fix WPOS 90e5a37 r300g/swtcl: fix secondary color and back-face color outputs 76034aa r300g: decouple drawing code and two-sided stencil refvalue fallback 1345c5b r300g/swtcl: handle large index count properly 3a6fd21 r300g/swtcl: force vertex prefetching for non-indexed primitives 55a6d37 r300g/swtcl: move emitting AOS to prepare_for_rendering 6ca3f86 r300g/swtcl: do not use u_upload_mgr and do not compute max_index 1bdbc0e r300g: fix fence referencing f0896e7 r300/compiler: implement SGT+SLE opcodes e6a8513 r300g: more efficient finish + fix comments 2c072c8 r300g: implement fake but compliant fences 876de34 r300g,util: remove pipe_surface from the util_blitter_copy interface and clean up 59e51d9 r300g,util: remove pipe_surface from the util_blitter_fill interface and clean up
Could you please try these one by one in a bottom-up fashion? Don't forget to type "sync" before you expect a hardlock. Once you find the first bad commit, go one commit back and try again. Then please give a report. Thank you.
