I just started having some really odd problems with a -STABLE I built
this afternoon. /dev/console seems to be blocking when I use the
serial port. I noticed since syslogd(8) did not seem to be working. I
brought it up in debug and it would get caught on the first entry with
/dev/console and just stick there,
# syslogd -ds -vv
sending on inet and/or inet6 socket
off & running
init
cfline("*.err;kern.debug;auth.notice;mail.crit /dev/console", f, "*", "*")
syslogd: /dev/console: Interrupted system call
logmsg: pri 53, flags 4, from blossom, msg syslogd: /dev/console: Interrupted system
call
I removed all of the /dev/console lines one by one. Each time I ran
syslogd(8) it would get caught at the next. It's now running fine with
all /dev/console lines commented out.
Just to see if it wasn't syslogd(8) I just did,
# echo "hello" > /dev/console
And it looked like I've hung that shell up hard.
Then... I quit the tip(1) sesssion I had going in another window and
the echo finished. I killed syslogd(8) and started it again with all
of the console lines in place and it is fine...
But now, if I try to start tip(1) again,
# tip -9600 cuaa0c
tip: /dev/cuaa0: Device busy
link down
Something seems broken. Note,
# ls /var/spool/lock
LCK..cuaa1
That's the lock on the modem, not the line to the other machine which
is on cuaa0. Also,
# ls -ali /dev/cua*0 /dev/console /dev/tty*d0
6334 crw--- 1 root wheel 0, 0 Jun 24 00:38 /dev/console

7375 crw--- 1 root wheel28, 32 Jun 23 15:06 /dev/ttyid0
7376 crw--- 1 root wheel28, 64 Jun 23 15:06 /dev/ttyld0
# fstat | egrep '(cua.*|tty.*d)0'
#
Any ideas? Not being able to use tip(1) to access other machines via
serial console is annoying.
