mgetty and 6.0-RC1

Hello!

I have strange problems after upgrading system from BETA5 to RC1.
After upgrade i see the following messages  in mgetty log and on serial console and mgetty does not work


10/15 18:59:04 ad1  mgetty: interim release 1.1.33-Apr10
10/15 18:59:05 ad1  mod: cannot make /dev/cuad1 stdin: Bad file descriptor
10/15 18:59:05 ad1  open device /dev/cuad1 failed: Bad file descriptor
10/15 18:59:05 ad1  cannot get terminal line dev=cuad1, exiting: Bad file descriptor

systems sources were "cvsupped" on 14/10/2005
and mgetty was installed from ports


What can i do to solve this problem ?
