I don't know if it is the same problem, but the Lenovo notebooks Lenovo E585
and Lenovo E485 with Ryzen 5 2500U or Ryzen 7 2700U also do not boot on Linux.
This is very frustrating, because you have to add command lines to GRUB make
them even able to boot on Linux:
ivrs_ioapic[32]=00:14.0 ivrs_ioapic[33]=00:00.1
and
spec_store_bypass_disable=on or spec_store_bypass_disable=seccomp
Otherwise Linux does not boot.
Thanks to evilazrael who found that workaround, otherwise still no-one would be
able to boot a Linux distribution on the laptop.
The initial analysis from him you find here:

An ongoing discussion of the case you find here:
https://forums.lenovo.com/t5/ThinkPad-11e-Windows-13-E-and/ThinkPad-E485-E585-Firmware-bug-ACPI-IVRS-table/m-p/4191484
It would be nice if it would be fixed, because many user will relinquish using
Linux if it does not boot on the first time, and also all others users need a
fix, because the workaround may reduces performance and increases power use.
