I think that I may find the reason: ================================ # ls -l /sys/firmware/acpi/tables/ total 0 -r--------. 1 root root 0 Nov 2 14:23 APIC -r--------. 1 root root 0 Nov 2 14:23 DSDT drwxr-xr-x. 2 root root 0 Nov 2 14:23 dynamic -r--------. 1 root root 0 Nov 2 14:23 FACP -r--------. 1 root root 0 Nov 2 14:23 FACS -r--------. 1 root root 0 Nov 2 14:23 HPET -r--------. 1 root root 0 Nov 2 14:23 SSDT # ls -l /sys/firmware/acpi/tables/dynamic/ total 0 ================================ The kernel only loads one SSDT. I use iasl to look at the content of SSDT, and find that it is ssdt-proc.dsl. The kernel does not load ssdt-pcihp.dsl.
