SUMMARY: E450 won't boot with APC SmartUPS

Consensus is that the problem is caused by getty and the UPS software both
running on the same serial port. Solution is to either redefine the console
or use a splitter cable on the E450, which has a combined serial port as
opposed to two separate A/B connections.

As usual, the list produced a better response in a shorter time than vendor

Original question below:-

> Apr 27 11:38:39 myhost unix: envctrl: ignoring debug enter sequence
> Apr 27 11:39:32 myhost last message repeated 1182 times
> Apr 27 11:40:01 myhost login: REPEATED LOGIN FAILURES ON /dev/console
> Any ideas as to how I can get this working. I have previously used this
