Using the wrong one on the wrong BIOS is not a good idea. Would you mind sharing your ideas and at least post the diff of your debug and the original DSDT. Some info about 10.3 (a lot SUSE users do not know how to compile a kernel): - DSDT can be overridden without kernel recompilation: http://powersave.sourceforge.net/powersave/DSDT.html - Since 10.3 OpenSuSE kernel versions have ACPI_DEBUG=y compiled in by default The correct fix for the broken 1503 BIOS is this: Compilation complete. 0 Errors, 5 Warnings, 0 Remarks, 1097 Optimizations [EMAIL PROTECTED]:~/dsdt/asus_bug_325995_bios_1503> diff -u DSDT.dsl DSDT.dsl.modif --- DSDT.dsl 2008-01-14 17:57:32.094872000 +0100 +++ DSDT.dsl.modif 2008-01-15 11:32:50.497733000 +0100 @@ -17,8 +17,6 @@ */ DefinitionBlock ("DSDT.aml", "DSDT", 1, "NVIDIA", "AWRDACPI", 0x00001000) { - External (\_PR_.CPU0) - Scope (\_PR) { Processor (\_PR.C000, 0x00, 0x00000000, 0x00) {} @@ -8988,7 +8986,7 @@ Name (_PSL, Package (0x01) { - \_PR.CPU0 + \_PR.C000 }) Name (_TSP, 0x3C) Name (_TC1, 0x04) I could reproduce and get the exact stack backtrace on a totally different machine (with passive trip point, _PSL support), by modifying the reference returned by _PSL to something invalid (and compile it with iasl -sa -f).
