In cases where console is on a separate serial port, does panic string
still has to go to BMC ? I have a scenario where the
interface between host processor and BMC is serial and there is another
serial port on host that is the console.
Thanks for all your replies.

The panic time operations are a more important thing than you might
imagine. Most customers who care about reliability want to take kernel
coredumps and use the IPMI watchdog. You can't extend the watchdog time
nor touch the watchdog during a coredump unless you can use the driver
at panic time.
