Help, I need some advice on ACPI. My system has been randomly crashing for some time in 9.1 and now in 9.2 :-( not had more than a few hours uptime for a long time. But by starting in failsafe mode, I can work quite happily with no crashes. I'm guessing from other posts that this is probably a combination of the nvidia drivers and my systems ACPI. I followed http://acpi.sourceforge.net/wiki/index.php/SUSE%209.0%3A% 20HOWTO%20load%20custom%20DSDT%20table%20%28you%20don%27t%20need%20to% 20recompile%20your%20kernel%29?action=BackLinks as far as recompiling the original DSDT table and I get the following: <Snip> eheath@espresso:/tmp> /usr/sbin/iasl -tc dsdt.dsl Intel ACPI Component Architecture ASL Optimizing Compiler / AML Disassembler version 20040220 [Oct 2 2004] Copyright (C) 2000 - 2004 Intel Corporation Supports ACPI Specification Revision 2.0c dsdt.dsl 358: Method (_WAK, 1, NotSerialized) Warning 2026 - ^ Reserved method must return a value (_WAK) dsdt.dsl 4551: Store (Local0, Local0) Error 1013 - ^ Method local variable is not initialized (Local0) ASL Input: dsdt.dsl - 5260 lines, 151118 bytes, 2196 keywords Compilation complete. 1 Errors, 1 Warnings, 0 Remarks, 473 Optimizations <Snip> If I attempt to fix this and load it in the Initrd, am I basically setting myself up for a world of pain? (I dont know assembler yet!) Also, by running with ACPI disabled am I likely to encounter any issues other than the box not powering off on shutdown? The admin guide suggests that 64bit boxes rely heavily on ACPI! Any advice greatfully received. Ed
