The same error messages appear on my XPS 15 9570 as well. They are present also when trying to disassemble the ACPI tables using `iasl -da`. It appears to be a conflict between the SSDT with ID "xh_cfhd4" (SSDT6) and the DSDT. Both appear to define _UPC and _PLD for the devices reported above: HS01 to HS12, USR1 and USR2, SS01 to SS10.
same on a 7530, on Ubuntu 19.10, and affected me resuming from several live distributions, as well. Over a hundred AE already exists and object creation errors, and won't resume... then I have to uncleanly shutdown, and boot from off. There's a new linux-firmware today; I'm hoping that fixes it.
