I am fairly confident that ACPI is supported by my laptop, because I have read several references to it working on it, and the BIOS-provided physical RAM map mentions ACPI as well. However, at boot, I get: ACPI: RSDP (v000 Acer ) @ 0x000ec2d0 >>> ERROR: Invalid checksum and later on, ACPI: Subsystem revision 20050211 ACPI: Interpreter disabled. and APM loads instead. If I compile a kernel sans APM, then I get no PM. Trying pnpacpi=off, pci=routeirq, apm=off, and acpi=force have done nothing. There is not even a /proc/acpi ! This is problematic because my laptop thinks there are no batteries now, and suspending freezes the machine on lid close (though running a script for it succeeds . . . unless I try to close the lid!) I am using Ubuntu Linux 5.04. Vanilla kernels have no better luck then theres. What can I do?
