Content-Type: text/plain; charset="utf-8"
Run motion in gdb, set a breakpoint on ioctl, and type 'fin'. If the warning
message appears, type 'bt' to see where the call was from. If the warning
message doesn't appear, press 'c' to continue.
(May require quite a degree of patience before you get to the problem one!)
