Hi Alexey, I have made the changes that you recommend and am also using the latest 2.6.17.13 kernel. The output from IASL is now: # iasl -tc ../dsdt.dsl Intel ACPI Component Architecture ASL Optimizing Compiler version 20051216 [Jan 9 2006] Copyright (C) 2000 - 2005 Intel Corporation Supports ACPI Specification Revision 3.0 ../dsdt.dsl 5350: If (Or (PLCY, PLCY, Local7)) Warning 2097 - ^ Statement is unreachable ASL Input: ../dsdt.dsl - 5434 lines, 178315 bytes, 2003 keywords AML Output: DSDT.aml - 17187 bytes 642 named objects 1361 executable opcodes Compilation complete. 0 Errors, 1 Warnings, 0 Remarks, 534 Optimizations # I patched the kernel to allow a DSDT table to come from the initrd image as per: http://gaugusch.at/kernel.shtml This worked fine and I now see the corrected DSDT table being loaded. # dmesg Linux version 2.6.17.13.rwl2 (root@deb1) (gcc version 3.3.5 (Debian 1:3.3.5-13)) #1 Fri Sep 15 21:18:15 BST 2006 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009f800 (usable) BIOS-e820: 000000000009f800 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000001f7f0000 (usable) BIOS-e820: 000000001f7f0000 - 000000001f7f3000 (ACPI NVS) BIOS-e820: 000000001f7f3000 - 000000001f800000 (ACPI data) BIOS-e820: 00000000e0000000 - 00000000f0000000 (reserved) BIOS-e820: 00000000fec00000 - 0000000100000000 (reserved) 0MB HIGHMEM available. 503MB LOWMEM available. found SMP MP-table at 000f5400 On node 0 totalpages: 129008 DMA zone: 4096 pages, LIFO batch:0 Normal zone: 124912 pages, LIFO batch:31 DMI 2.3 present.
