Greetings,
I do have an issue with FreeBSD 5.1-RELEASE (i386) and a serial
console. I can see the boot messages, console messages and a login
prompt. I can type a username, after that it shows the password prompt
and at that point things stop working as expected.
After a while 'ps' shows that the login is the front-process (1059 in
the output below) for ttyd0 but it becomes idle regardless any console
input:
# ps -ef | grep login
483 v0 Is 0:00.02 login [pam] (login)
1059 d0 I<s+ 0:00.01 login
When I kill the login process the 'getty process' is started as
front-process for ttyd0:
# ps -ef | grep ttyd0
1085 d0 Ss+ 0:00.00 /usr/libexec/getty std.9600 ttyd0
Again the login prompt appears in the terminal connected to the serial
console.
ps also shows that the login process raised CPU scheduling priority
('<'). Tests show that this process does that when waiting for a
password in a VGA-console. So I guess the login process is waiting for
a password but somehow it does not receive anything from the serial
port. Hense it becomes idle.
However, console messages (like: "login: Nov 29 21:37:46 cyclone login:
ROOT LOGIN (root) ON ttyv1") are redirected fine to the serial console.
Does anyone have an idea what might go wrong here?
Thanks in advance, Arien
