Got this a bit further by adding this to the config:

So I guess that the ACPI stuff is done, and we're going to look at init-ing the
subsystems.
But how do I translate the number to a name?
Look at sys/sys/kernel.h:
SI_SUB_VM = 0x1000000, /* virtual memory system init */
Did not find that, so thanx for the hint.
I guess it is the virtual memory init, since there is only on place that calls
vm_mem_init.
And that is from the sysinit chain.
But I would expect things to be really bad if the system hangs in the VM
initialisation?
How much RAM does the system have?
You can try reducing memory addressed by the kernel with another loader knob:
hw.physmem=4G
But this was an even better hint... I set it too 1G to even avond the
4Gb limit.
Board should have 16Gb of mem....
It now get all the way to mounting the USB stick...
This what could be the problem now?

subsystem 1000000
vm_mem_init(0)... vm_mem_init:131

I have both tried 1Gb and 4Gb.
Could be that one of the DIMMs is defect, not seated correctly, or in
the wrong slot??
This would suggest that 4Gb is missing:
