When mplayer hangs while skipping through a video, strace shows: futex(0x25ec004, FUTEX_WAIT_REQUEUE_PI_PRIVATE, 17, NULL, 0x25ec9d0 When GNOME shell last hanged the screen completely, strace also had something like above: futex(XXXX, FUTEX_WAIT_REQUEUE_PI_PRIVATE, 17, NULL, XXX Pretty sure the 17 + FUTEX_WAIT_REQUEUE_PI_PRIVATE were the same. Are we missing maybe some glibc patches that Fedora did apply? Note: I'm wondering if futex is glibc or kernel material. But as I removed all old kernels, cannot test that theory anyway. -- Regards, Olav
