Dear Maintainer,
I am reporting ACPI BIOS errors occurring on my laptop running Debian.
System Detail
# dmidecode 3.7
Getting SMBIOS data from sysfs.
SMBIOS 3.5.0 present.
Handle 0x0001, DMI type 1, 27 bytes

System Boot Information
Status: No errors detected
kernel version
7.0.4+deb14-amd64
Notebook Model
HP 250 15.6 inch G10 Notebook PC
uname -r
7.0.4+deb14-amd64
Bios Version:
F.24
## Problem description
During system boot, the kernel logs ACPI-related firmware errors. These appearm
consistently in `dmesg` and may indicate BIOS/firmware ACPI table issues or
kernel ACPI parsing problems.
## Observed errors
From kernel logs:
* ACPI BIOS Error messages
* AE_NOT_FOUND errors
* Occasional AML-related warnings
Example (from dmesg):
```
ACPI BIOS Error (bug): Could not resolve symbol / method ...
AE_NOT_FOUND (2020xxxx)
```
## System information
* CPU: Intel Alder Lake / Raptor Lake platform
* Kernel: (run `uname -r` and insert version)
* BIOS version: (from `dmidecode`)
* Distribution: Debian
## Steps to reproduce
* Boot system normally
* Observe kernel log using:
```
dmesg | grep -i acpi
```
## Expected behavior
No ACPI BIOS errors should appear during boot, and ACPI tables should be parsed
cleanly by the kernel.
## Actual behavior
ACPI BIOS errors are printed during boot and may indicate firmware
incompatibility or kernel ACPI handling issue.
Regards,
Nahid Hasan
