This is rather complicated and the bug seem to sit at early initialization
already.

I first hoped this gets fixed through this patch (which I will now also be
added to 10.3):
ACPICA: fix acpi-cpufreq boot crash due to _PSD return-by-reference
http://bugzilla.kernel.org/show_bug.cgi?id=5328
http://bugzilla.kernel.org/show_bug.cgi?id=9429

It does not fix it, but it is related..., after applying you get:
dsobject-0129 [00] ds_build_internal_obje: Ignoring unresolved reference in
package [_PSL]
(when setting debug level to info)

The dangerous part is that if a package contains a reference which does not
exist, an invalid node pointer is added:
Reference handle: ffff810037fde510 - Reference type 0
Reference handle: ffff810037fda7d0 - Reference type 0
Reference handle: ffff810037fdaf50 - Reference type 0
Reference handle: ffff810037fd3470 - Reference type 0
Reference handle: ffff810037fd33f0 - Reference type 0
Reference handle: ffff810037fd3370 - Reference type 0
Reference handle: ffff810037fd32f0 - Reference type 0
Reference handle: ffff810037fd3270 - Reference type 0
Reference handle: ffff810037fd3fd0 - Reference type 0
Reference handle: ffff810037fd3f50 - Reference type 0
Reference handle: ffff810037fd3ed0 - Reference type 0
Reference handle: 4d52454854584e4c - Reference type 0

The last one is probably uninitialized memory -> danger (for the not found
reference).
You find the debug used for this attached in the next comment.

First I added two (not existing) processor objects returned in the _PSL
package.
The first one had the invalid memory: 4d52454854584e4c, the second was zero
which led to "Invalid passive trip point". It seems as if the bug is to find
this condition and initialize the handle with zero, but this internal
interpreter code is a hard nut and I need to reboot for each try -> I give up
here now. I still can provide further info or do some testing to finally
resolve this.
