_CST:
                           Package (0x04)
                            {
                                ResourceTemplate ()
                                {
                                    Register (FFixedHW,
                                        0x01,               // Bit Width
                                        0x02,               // Bit Offset
                                        0x0000000000000052, // Address
                                        0x03,               // Access Size
                                        )
                                },

                                0x03,
                                0x8C,
                                0x0A
                            }


This AML verifies that ATM-C6 should be entered with sub-state 2, ie 0x52,
and the 0x8C is 140usec worst case latency.

re: comment #14
thanks for verifying that the patch gives you c6 on both AC and DC.

Interesting.  I that is either an ACPI BIOS bug
or a Linux kernel ACPI bug.  Mis-guided ACPI-BIOS feature anyway.

dmesg in comment #1 show that the dynamic SSDT's are loaded.
Very strange that they are not visible in /sys/firmware/acpi/tables/dynamic
If you could, it would be ideal to file a new bug for that issue
in the ACPI category.

Re: comment #18
the patch builds for me on top of the latest git tree.
I'd supply a back-port, but the reality is that all the patches
underneath it are going to .stable anyway; so mixing their
order would just complicate things.
