Hi, Victor Will you please attach the output of acpidump? Please also attach the following output: > cat /sys/firmware/acpi/tables/dynamic/SSDT1 >ssdt1 > cat /sys/firmware/acpi/tables/dynamic/SSDT2 >ssdt2 Please boot the system with the boot option of "cpufreq.debug=0x07" and attach the output of dmesg. Thanks.

an't make cat /sys/firmware/acpi/tables/dynamic/SSDT1 > ssdt1 because directory /sys/firmware/acpi/tables/dynamic/ is empty.
Hi, Victor I check the acpidump and find that there is no _PSS object in ACPI table, which is required by acpi_cpufreq driver. So IMO this is a bios bug. Will you please try to check whether the updated bios is available and see whether it can be fixed. Thanks.
As this is a BIOS bug, this bug will be rejected as Documented. Thanks.
