I have a number of PowerEdge 2550 servers. All are setup with serial console on ttyS0 @ 9600. One group uses a (old) Portmaster device for console access, the other group uses a Cyclades device. Only those servers using the Portmaster device exhibit the garbage problem. The Cyclades group never displays garbage on boot.
