That might give you a valid backtrace, you could also use kgdb to 'really' debug it, though I'm not really used to kgdb yet. > camera->v4l.priv = (void*)camera; I don't think you're supposed to use the priv field here. Using fops should give you a 'struct file *file' on open(), use file->private_data for these purposes. On open(), just search the global array of registered devices for which device was being opened. That way, you don't need to use the priv field. HTH, Ronald -- Ronald Bultje <rbultje@xxxxxxxxxxxxxxxxxxx> Linux Video/Multimedia developer
