ACPI BIOS error on Ubuntu

This page from the Acer community may help. Also a Google search for ACPI BIOS error on Ubuntu turns up a large number of suggestions. One common suggestion is to update to the latest BIOS.

There was a BIOS update posted 4 days ago on August 8th. That update can be found here.

Vostro 5402 with the latest BIOS.

The problem is still there.

I have the same issue with a Dell Inspiron 3880 Desktop. I updated the BIOS to version 1.14.0, did not help.

Did you find any workaround? I encounter the same issue with Vostro 5402, 1.16 latest bios

My Precision 5550 with the latest bios, as well.

I'm running into the same issue with my dell precision 7750. I have the latest bios update. It's not something the linux kernel people can fix so it must be a bug in the bios.

Dell XPS 8940 purchased 02 Dec 2021.
Linux Mint 21.1 installed and operating without issue.
BIOS verified through BIOS info at startup is 2.11.1.

At start the following is displayed:

I would really prefer to see a fix from Dell.

XPS 15 9500 + arch linux 6.2.12-arch1-1

Dell WD19TB Thunderbolt Dock

latest bios/firmware/os

boot always finishes with:

ucsi_acpi USBC000:00: unknown error 0

ucsl_acpi USB000:00: UCSI_GET_PDOS failed (-5)

Just for context

Dell Precision 5750 running Ubuntu 22.04 LTS with the official Linux 5.19.0-46-generic and NVIDIA UNIX x86_64 Kernel Module  470.199.02

I have been seeing this error with many firmware versions, including the latest 1.25.0:

I'm getting the same errors filling up my /var/log/kern.log file on a Dell Precision 7760 running Ubuntu 20.04 with the  vmlinuz-5.15.0-88-generic kernel.

Over 60 MILLION log messages per day.
Does anyone at Dell read these messages?  An ongoing problem reported for over a year now, and still no solution??? 

OptiPlex 3070 running Fedora 39 with Dell U2723QE monitor.  Since upgrading today to  6.6.8-200.fc39.x86_64 kernel,  journalctl has 100's of these ACPI Errors. 

i fixed same issue with changing sata mod in bios from raid to ahсi.

F2 -> System Configuration -> SATA Operation -> AHCI

i may have found another setting in BIOS that might block the installation of distro with python scripts implemented

disable Intel© SGX™ Enabled

F2 -> Intel© Software Guard Extensions™ -> Intel© SGX™ Enabled -> Disabled

(i have only seen this option on DELL machine BIOS)

the ACPI error messages still shows up, but they are harmless and the distro installed no problem

I have an Inspiron 5515 and it has been doing it as well with no fix in sight. It definitely started after a bios update. I also have a mini pc also running an AMD Ryzen 7 and it has no issues or errors whatsoever. This is a Dell issue, most likely a software issue they're not willing to fix. 

And considering this has been going on this long and Dell doesn't seem to want to acknowledge it this may be my last laptop with them.. I will pay more and go with a linux laptop from the start.
