Kernel panic - not syncing: Attempted to kill init!

Please note the "x3'" trash characters right in the beginning.

I guess I didn't configure the OF serial right in the .dts but it still
shouldn't crash. My .config is attached.

Try disabling CONFIG_SERIAL_OF_PLATFORM.  I don't think it means what you 
think it means.

Thanks, disabling CONFIG_SERIAL_OF_PLATFORM helps. but it still shouldn't crash...

That's a bug in the OF serial driver.  It's expecting fields in the serial 
node that don't exist.  You are right, however.  The driver should at least 
check for NULL pointers.  If I had any hardware that used that driver, I would 
fix it myself.

Ok, that is a NULL pointer access, probably somewhere in the

device tree entries for your serial ports so we can see what
goes wrong there.

One potential problem that I can see is a missing 'current-speed'
property in your tree, which would cause this behavior. It looks
like many device trees set this, but it is not required by all
bindings. If that's the case, the patch below should fix your
problem, but you probably want to set the current-speed anyway,
according to your boot loader settings.

The device tree is the default one which comes with the kernel:
paulus.git/arch/powerpc/boot/dts/mpc8540ads.dts
which contains:

                 serial@4500 {
                         device_type = "serial";
                         compatible = "ns16550";
                         reg = <4500 100>;       // reg base, size
                         clock-frequency = <0>;  // should we fill in in uboot?
                         interrupts = <2a 2>;
                         interrupt-parent = <&mpic>;
                 };

                 serial@4600 {
                         device_type = "serial";
                         compatible = "ns16550";
                         reg = <4600 100>;       // reg base, size
                         clock-frequency = <0>;  // should we fill in in uboot?
                         interrupts = <2a 2>;
                         interrupt-parent = <&mpic>;
                 };

That's correct. Should be fixed in all .dts' ?

How should someone know, when it's really needed and when not?

I think there was no need to set it again, because of: console=ttyS0,115200
But I'll verify...

Ack! However, I changed it similar to the available code.
No idea what's better here. At least it should tell the user:

Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled
serial8250.0: ttyS0 at MMIO 0xe0004500 (irq = 42) is a 16550A
console [ttyS0] enabled
serial8250.0: ttyS1 at MMIO 0xe0004600 (irq = 42) is a 16550A
of_serial e0004500.serial: no current-speed property set
of_serial e0004600.serial: no current-speed property set

Patch attached.

It depends a lot on how the systems are used. current-speed only makes
sense if there is a boot loader that also does some serial I/O at a
speed it sets up itself.

The point of current-speed is that the kernel can tell what bitrate
was used by the boot loader and set up the same speed so that your
terminal emulation does not get garbled output when changing from
boot loader messages to kernel messages.

When current-speed is set, you don't need to override the speed at the
command line.

This looks wrong. Since the current-speed property is not mandated by open =
firmware,
we should not error out here, but simply use the setting from the command l=
ine
or whatever other defaults can be used. Not setting port->custom_divisor at=
 all
should do the job.

Understood... but then, my console just stops / gets reinitialized to some unknown
baudrate when I get to of_serial.c. :-(
