Unfortunately I cannot fetch the crash log as I am not having access to a serial line (using vga console) and in my setup mtdoops is not working somehow. Sequence is v4l2_ioctl->video_usercopy->__video_do_ioctl->v4l_s_ctrl->v4l2_s_ctrl->set_ctrl_lock->try_or_set_cluster->si4713_s_ctrl->si4713_set_power_state->mutex_lock_nested->lock_acquire. I 'd need to spend some time on it to understand better your patches and help you to get this working. And for that I'd prob need to spend some time to either hack a serial line or get mtdoops to work :-) > Regards, > > Hans -- Eduardo Bezerra Valentin -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
