This support (bugzilla 5653) shipped starting in 2.6.18, and I sent it to Adrian for 2.6.16.stable -- and it appears it will pop out in 2.6.16.31. Re: your 16 core machine running 2.6.9... What does /proc/acpi/processor/*/power say? I would expect it to say C1 only. I would not expect this box to grow deeper C-states upon the support above. The only SMP boxes with C-states deeper than C1 that I'm aware of today are laptops. cheers, -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
