Modules-load.service list problem

I was checking the services that load when Linux starts and I found, I think, two errors related only to the SSD and the sound card.
The first error I get related to this

[    0.301623] ACPI Error: Needed type [Reference], found [Integer] (____ptrval_                                                                                      ___) (20220331/exresop-66)
[    0.301634] ACPI Error: AE_AML_OPERAND_TYPE, While resolving operands for [Op                                                                                      codeName unavailable] (20220331/dswexec-431)
[    0.301643] ACPI Error: Aborting method \_PR.CPU0._PDC due to previous error                                                                                       (AE_AML_OPERAND_TYPE) (20220331/psparse-529)

The solution he found in the meantime was using the command libata.noacpi=1 modifying grub
I understand that it is a temporary solution while I investigate if it has anything to do with the Bios.

The second error is the sound, but it has something to do with power management because my speakers work without any problem and I haven't had any issues.

[    5.402116] snd_hda_intel 0000:01:00.1: Unable to change power state from unk                                                                                      nown to D0, device inaccessible

Then I got another related error as well. "DMAR: DRHD: handling fault status reg 3"
the solution was  the command intel_mmu=off

I want to clarify that my laptop turns on in 10 seconds without any problem and I had no performance issues or anything.

Startup finished in 1.451s (firmware) + 1.466s (loader) + 2.932s (kernel) + 5.039s (userspace) = 10.890s
graphical.target reached after 4.950s in userspace.

As always, I appreciate any help.
