yes, this happened to me (three times I think..)
This must be in the archives.
The problem is that the default /etc/ttys doesn't
enable your default console, e.g. from my rx2600
% dmesg|grep uart
GDB: debug ports: uart
GDB: current port: uart
uart0: <16550 or compatible> mem 0xf4051000-0xf405100f irq 82 at device 1.0 on pci224
uart1: <Non-standard ns8250 class UART with FIFOs> on puc0
uart1: console (9600,n,8,1)
uart2: <Non-standard ns8250 class UART with FIFOs> on puc0
uart3: <16550 or compatible> iomem 0xff5e0000-0xff5e0007 irq 34 on acpi0
uart4: <16550 or compatible> iomem 0xff5e2000-0xff5e2007 irq 35 on acpi0
uart4: debug port (9600,n,8,1)
i.e. I need to enable logins on ttyu1, so I have in /etc/ttys:
ttyu0 "/usr/libexec/getty std.9600" vt100 on secure
ttyu1 "/usr/libexec/getty std.9600" dialup on secure
I think you should be able to connect to MP
via ethernet still, provided you know the
ip address of your MP.
