Hi!
Since at least yesterday my actual -current systems (cobalt, amd64;
-current kernel and userland, tried it with sources from yesterday and
today) both show general ipv6 problems:
Though ipv6 configured as before ipv6 connectivity seems broken, e.
g.:
  $ ssh ::1
  ssh: connect to host ::1 port 22: Address already in use
though 'someone' is listening:
  $ netstat -af inet6
  Active Internet6 connections (including servers)

At boot time several processes complain about:
  mountd[233]: Cannot bind to reserved port 0 (Address already in use)
Does anybody else see this problem?
