Hmm, it is pretty empty on thinkpad x60, too, and s2ram actually works here: root@amd:/home/pavel# acpidump -t FACS FACS @ 0x7f6f4000 0000: 46 41 43 53 40 00 00 00 95 15 00 00 00 00 00 00 FACS@........... 0010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0020: 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ ...and iasl actually segfaults here, too :-( root@amd:/data/l/kohji# iasl -d FACS.x60.aml Intel ACPI Component Architecture AML Disassembler version 20061109 [May 18 2007] Copyright (C) 2000 - 2006 Intel Corporation Supports ACPI Specification Revision 3.0a Loading Acpi table from file FACS.x60.aml Segmentation fault (core dumped) root@amd:/data/l/kohji# ...hmm, if it is buffer overflow, we have security problem in iasl. Anyway, how do I decode FACS?
