[Bug] ACPI BIOS errors - MECHREVO WUJIE15XA laptop (AMD Phoenix3)

Hi,

On a MECHREVO WUJIE15XA laptop (AMD Phoenix3, BIOS v111), the
following ACPI errors appear at boot:

  ACPI BIOS Error: Failure creating named object [\_SB.PCI0.GPP6.WLAN._DSM], AE_ALREADY_EXISTS
  ACPI BIOS Error: Failure creating named object [\_SB.PCI0.GPP6._S0W], AE_ALREADY_EXISTS
  ACPI BIOS Error: Failure creating named object [\_SB.PCI0.GPP6._PRW], AE_ALREADY_EXISTS
  ACPI BIOS Error: Failure creating named object [\_SB.PCI0.GPP6.WLAN._S0W], AE_ALREADY_EXISTS
  ACPI BIOS Error: Could not resolve symbol [^^^^NPCF.ACBT], AE_NOT_FOUND
  ACPI Error: Aborting method \_SB.PCI0.SBRG.EC0._Q83

The first four are duplicate named objects in the DSDT for the
WLAN device. The last two affect EC query method _Q83.

Kernel: Linux de 6.12.96+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.96-1 (2026-07-20) x86_64 GNU/Linux
DMI: MECHREVO WUJIE15XA
BIOS: American Megatrends International, LLC. v111

Is this a known BIOS bug, or is a kernel workaround possible?

Full dmesg output available on request.
