The lockup happens in the same place, as in case of bug #19693: > I made little debugging. Normally on plain X R600PrepareSolid is called from time to time and it works fine. When I start SMplayer R600PrepareSolid is also called but in never returns. R600PrepareSolid sub-calls RHDDRMCPBuffer and that RHDDRMCPBuffer lockups in "for" loop. > This "for" loop starts counting from 0 to 2000000 and every drmDMA() call takes 0.1 sec. As the result system lockups. Bug smashed with just one simple patch. Thank you Alex! http://cgit.freedesktop.org/xorg/driver/xf86-video-radeonhd/commit/?id=85e406dd |
