I haven't been able to boot with no params with 1.13. bios, but now I can make it work with:
"text radeon.modeset=0 amdgpu.runpm=0 mem_encrypt=off ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 rcu_nocbs=0-7 idle=nomwait acpi_enforce_resources=lax"
With these params everything works fine - gpu, suspend/resume, touchpad, function keys, normal cpu usage ....
Secure boot, enabled, also.
