This can happen if some program, e.g. an early init script, writes to
/dev/null before the device node for it is created. In this case,
redirection (foobar > /dev/null) will create it as a regular file.

I don't really have an explanation or a solution. To debug the problem,
reboot with init=/bin/bash added to the kernel command line and run the
scripts in /etc/rcS.d, one at a time (/etc/rcS.d/Swhatever start).
Check /dev/null after each script.
