root '/dev/disk/by-partuuid/' doesn't exist or does not contain a /dev

[DMårt]

I get this issue in the booting process of Linux. Then nothing else happens, except outputs from Optee.

F/TC:? 0 pta_scmi_ocall:207 Posting MSG message on channel 0
root '/dev/disk/by-partuuid/e91c4e10-16e6-4c0e-bd0e-77becf4a3582' doesn't exist or F/TC:? 0 regulator_set_voltage:202 vddcpu 800000uV
does not contain a /dev.

 Question:

I assume that this is a common issue for the MP2 platform. Is there anyway I could fix this? Extlinux.conf perhaps? 

I have the same clock settings as DK.
