Obviously getkey is being used as it does respond properly to a return. I =
am beginning to suspect that menu_timeout_enabled is zero. I believe addin=

firm my suspicion that menu_timeout_enabled is set to 0. It is only displa=

After much digging, I now know what it going on, but not why. When getkey =
is called the first time, menu_timeout_enable is set to one. However, it i=
s set to zero on every check after that. In getkey after the comment "Was =
a key pressed" is a check of key to see if a key was pressed. It is return=
ing a decimal 7 (BEL). That then clears menu_timeout_enable and it then si=
ts there waiting for a valid key input. There is no keyboard plugged into =
the system. I have no idea how that BEL is being generated or even how to =
prevent it. Could it be possible that it comes from the serial console? I=
tend to doubt thats the case since the system hangs during boot when the s=
erial console is not connected. I suppose that I could put in a test for a=
key value that is not a control character, but that would only work until =
the next system update. I'd have to remember to put it back in each time. =
Thats not likely to happen. My memory is not that good. Whats interestin=
g is that I have 4 systems (i386) doing this and 1 system (i386) and 2 syst=
ems (amd64) not doing it. The only common thread is the 4 systems doing it=
are about 100 miles from me and the working ones are here.
