Created attachment 303668 [details] dmesg, acpidump and smbios packed into gzip'd tar Dear all, processing of ACPI tables fails for thermal zone(s) on boot for device HP Pro x360 435 G9 running HP BIOS Version: U80 Ver. 01.09.00 Release Date: 10/18/2022. It seems there is a thermalzone 'CHGZ' missing at least. Bug is probably related to #200999 since the system is a HP device, too. Please find attached the dmesg plus dumps of the acpi tables and the current smbios. Looking forward to get some guidance on resolving that issue. Best regards, Carsten
