>Description:

After upgrading to current, I can not log into this machine via ssh any
more:

sshd logs:

fatal: mm_pty_allocate: receive fds failed
Accepted publickey for martin from 192.168.111.60 port 65529 ssh2
error: mm_send_fd: sendmsg(6): Invalid argument
fatal: mm_answer_pty: send fds failed
error: close(s->ptymaster/0): Bad file descriptor
error: mm_receive_fd: recvmsg: expected received 1 got 0
fatal: mm_pty_allocate: receive fds failed

I have ptyfs mounted:
/dev/wd0a on / type ffs (soft dependencies, NFS exported, local)
kernfs on /kern type kernfs (local)
procfs on /proc type procfs (local)
ptyfs on /dev/pts type ptyfs (local)


>How-To-Repeat:
I didn't dare to update other machines to -current yet, no idea if this
is amd64 (or 64 bit) specific

>Fix:
n/a
