[parisc-linux] K380 partial success, the state of the port?

[Ryan Bradetich]

I looked through your log because this crash looked very familar to me
:(

> Kernel command line: root=/dev/sda2 HOME=/ console=ttyB0
palo_kernel=2/boot/vmlinux

Good you have palo set for the Serial Mux.

But I do not see the Serial Mux in the console log.  Can you verify that
the CONFIG_SERIAL_MUX and CONFIG_SERLIAL_MUX_CONSOLE are compiled into
your kernel?

I would bet this is your problem just from the dump output ... and
futher confirmed by lack of serial mux in your boot log.

Should look something like:

Serial mux driver (8 ports) Revision: 0.2
ttyB0 at MMIO 0xfff78800 (polling) is a Mux
.
.
.

Thanks,

- Ryan
