By "working" I mean no output is seen, nor is any input possible. Messages sent directly to the prom seem okay, i.e. at the'ok' prompt or via prom_printf() calls. I tried various incantations of the serial= option to noavail. This problem is only when linux is booted, if I shutdown the OS the console comes back and I can interact with OBP. It seems that if I power cycle the machine the serial console will work, but on subsequent reboots it does not. Has anyone else encountered this? The behavior is the same whether I am booting a 2.2.x or 2.3.x kernel. Any suggestions would be greatly appreciated. Thanks in advance, Pat -- Patrick O'Rourke orourke@missioncriticallinux.com
