Maybe this is another bug.
I'm always getting this error, and I have nothing connected to the serial port.
init: getty repeating too quickly on port /dev/console, sleeping 30 secs
Using pfSense-1.2.1-20081106-2246 with an ALIX2c3 and a Kingston 1GB CF.
Was this an upgrade? I would suggest reinstalling.
It is not an upgrade, it's a clean installation with an imported config file from m0n0wall.
The errors have stopped… it seems they appear right after a reboot, keep showing for some hours, maybe about a day and then stop.
I don't have the serial cable connected BTW.
