ACPI on an Acer TravelMate C100
Hello. 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
Quoted 1 line
Quoted 1 line
Quoted 1 line
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?
