Problem is only present with having a serial cable as extra heartbeat.
Cable is verified to be proper nullmodem cable.

Still I get:
Oct 02 14:13:41 noemic2 heartbeat: [27996]: info :  Link noemic1:/dev/ttyS0 up.
Oct 02 14:15:55 noemic2 heartbeat: [28008]: WARN :  glib: TTY write
timeout on [/dev/ttyS0] (no connection or bad cable? [see
documentation])
Oct 02 14:15:55 noemic2 heartbeat: [28008]: info :  glib: See
http://linux-ha.org/FAQ#TTYtimeout for details

Strange.
