I am trying to read the CPU information through "acpitool -c". And I get a message as: " Function Show_CPU_Info : could not read directory /proc/acpi/processor/ Make sure your kernel has ACPI processor support enabled. " I went to the kernel configuration, it appears to me it's already enabled. And there're two tick box stating "deprecated /proc/acpi files, deprecated power /proc/acpi directories". Whether I tick it or not doesn't couldn't generate a new /proc/acpi/processor/ So is there a way to bring this functionality back? P.S. I am using linux 3.2.0-23-generic kernel. Kevin Qiu
