** Summary changed: - ASUS Vivobook X3500PC BIOS 302: repeated ACPI AE_NOT_FOUND thermal sensor errors + ACPI BIOS Error: AE_NOT_FOUND and invalid thermal zones (0.1°C) on ASUS Vivobook Pro 15 X3500PC
** Description changed: I am using an ASUS Vivobook Pro 15 X3500PC/K3500PC running Linux Mint 22.3, based on Ubuntu 24.04. - - Affected package: - linux Current kernel: 7.0.0-28-generic Kernel package: linux-image-7.0.0-28-generic Version: 7.0.0-28.28~24.04.1 Origin: official Ubuntu noble-updates/main and noble-security/main repositories - Maintainer: Canonical Kernel Team Hardware: ASUS Vivobook Pro 15 X3500PC/K3500PC BIOS: X3500PC.302 BIOS 302 is the latest BIOS currently available from ASUS for this model. The ACPI errors have occurred since I started using Linux on this - machine. This is not a recent regression caused by kernel 7.0. + machine. This is NOT a recent regression caused by kernel 7.0. During every boot, the kernel reports repeated ACPI AE_NOT_FOUND errors involving undefined firmware symbols and thermal-zone methods. Representative errors include: ACPI BIOS Error (bug): Could not resolve symbol [\CTDP], AE_NOT_FOUND ACPI Error: Aborting method _SB.IETM.IDSP due to previous error (AE_NOT_FOUND) ACPI Error: Aborting method _SB.IETM._OSC due to previous error (AE_NOT_FOUND) The following thermal-zone objects under: _SB.PC00.LPCB.EC0.SEN1 _SB.PC00.LPCB.EC0.SEN2 _SB.PC00.LPCB.EC0.SEN3 _SB.PC00.LPCB.EC0.SEN4 also fail when evaluating these methods: _CRT _HOT _PSV _AC0 Examples include unresolved symbols such as: S1CT, S1HT, S1PT, S1AT S2CT, S2HT, S2PT, S2AT S3CT, S3HT, S3PT S4CT, S4HT, S4PT, S4AT Observed thermal-zone readings include: acpitz: approximately 43°C TCPU: approximately 41°C x86_pkg_temp: approximately 42°C SEN2: approximately 42°C SEN4: approximately 40°C However, SEN1 and SEN3 report invalid readings of approximately 0.1°C. The system remains operational: * thermald is active and running * CPU fan control works * CPU temperatures are normal * NVMe temperatures are normal * NVIDIA and Intel graphics drivers work * there are no PCIe AER errors * there are no NVMe errors * there are no reported memory errors * suspend and general power management appear to work normally thermald reports: sensor id 14: No temp sysfs for reading raw temp Polling mode is enabled - This appears to be caused by malformed or incomplete ACPI firmware - tables in ASUS BIOS 302. I am reporting it because the kernel may be - able to add a model-specific quirk or provide better handling of the - invalid thermal-zone definitions. + This seems to be caused by malformed or incomplete ACPI firmware tables + in ASUS BIOS 302. I am reporting it because the kernel may be able to + add a model-specific quirk or provide better handling of the invalid + thermal-zone definitions. Expected result: The firmware ACPI tables should be parsed without repeated AE_NOT_FOUND errors, and invalid SEN1/SEN3 thermal readings should either be ignored or handled safely. Actual result: Repeated ACPI BIOS errors are logged on every boot, and two thermal zones expose invalid 0.1°C readings.
