This means that cdevsw[maj]->d_open is bad (probably null) although cdevsw[maj] != NULL. This might be caused by a buggy or stale LKM. Driver LKM's tend to cause this problem if they are unloaded. Bash may trigger the problem because it does an opendir() on device files (but I thought I fixed this by not opening device files in opendir()). I wouldn't use LKMs for anything important. Bruce
