Created an attachment (id=31072)

dmesg for the latest 2.6.36-rc5 kernel

The most interesting part is the same:

[    0.158142] ACPI: BIOS _OSI(Linux) query ignored
[    0.163393] ACPI Error: Could not map memory at 0x000000007D422720, size 141
(20100702/exregion-178)

function
[    0.181379] ACPI: EC: GPE = 0x17, I/O: command/status = 0x66, data = 0x62


Also on bootable kernels with AE_NO_MEMORY error, powertop tells that power
usage (ACPI Estimate) of the whole system is unbeliveable 1.5W :)
