Yes, this is the problem. When a UART is specified as the console
using "console=uart,...", the console index is not initialized. This
causes the uart_console() check to mis-identify the port and we enable
sleep mode when we don't intend to do so. Not sure how to fix it yet,
but I assume we need to go back through after the serial ports are
enumerated, and un-suspend the console port. David, would you mind
trying this on the XR16L255x part? (ie. don't use console=ttyS, use
console=uart,...) Thanks,
Alex
