--- Comment #4 from Michel Dänzer michel@daenzer.net --- Created attachment 139718 --> https://bugs.freedesktop.org/attachment.cgi?id=139718&action=edit Print fpfn/lpfn values in ttm_bo_mem_space_debug
Can you rebuild the ttm.ko module with this patch applied, and attach the resulting dmesg output when the problem occurs again? It might shed some more light on why we fail to evict a BO to GTT, even though there seems to be enough space there.
