The changes I made from before was 1) I unmounted the USB disk and 2) I rebuild the xc5000 module where I removed the mutex_lock(&xc5000_list_mutex); and mutex_unlock(&xc5000_list_mutex); lines according to the discussion in the " ... em28xx: initial support for HAUPPAUGE HVR-930C again" thread. /Fredrik
