Sounds like a terminal setup problem.  (For one thing, it's not throwing the 
terminal into raw mode.)

It sounds like a problem with init logging to the serial console, actually.

Are you using a serial console?  In this case, init will keep an open 
filehandle for the serial console (for logging purposes), meaning another 
process has it claimed and is a session group leader and all that fun 
stuff....

Are you using config_syslogd?  If not, things get icky.  (Search init/init.c 
for the comment:

/* Take full control of the log tty, and never close it.
     * It's mine, all mine!  Muhahahaha! */

Which could easily screw you up.  Read console_init(), then message() in 
init/init.c.  (Bring a barf bag.)

Enabling CONFIG_SYSLOGD is probably the easiest fix...
