Can't enable ACPI (don't know how?)
ACPI seems not to be supported, so use apm to turn off the power at shutdown.

Hello :] Thanks for the feedback.

This is not nice. Unfortunatelly it's almost unreal to get support from the kernel team for 2.4 series kernels and searching in kernel sources & backporting might be pretty time consuming. Hopefully this will find it's timeframe one day.

If your hardware supports ACPI, then it's enabled by selection of the first entry in the GRUB bootloader. The second entry is marked with [acpi=off] and can be used for computers with broken or no ACPI support. No universal solution exists in this case and this needs to be tested and documented. Workarounds might exist.

I read somewhere that the 2.4 kernel has recently reached its end of life. Does this mean there is no official support any longer and that individual developers (like you) are on their own when it comes to fixing bugs? If so, it seems like a big job. So if these problems with usb detection are not too widespread then maybe you don't have to worry about it too much for now?

I wrote that because I thought ACPI might be supported, but looking at the messages below I guess that's not the case? Generally, on what type of hardware (or maybe what year?) does ACPI become commonly supported? Thanks for your input on this. I find it all very confusing...

Code:

dmesg | grep ACPI

ACPI: Unable to locate RSDP
ACPI: Subsystem revision 20040326
ACPI: Interpreter disabled.

The latest available 2.4.x kernel (currently used by us) is more than a year old and I don't expect new 2.4.x versions ... but it's still pretty sufficient for ancient hardware and we can maintain our local patches without being dependent on upstream ... just the human resources could be a problem. Not many developers want to maintain such an obsolete stuff :] Just crazy ones (like me).
I see one issue here ... and that's mixing of recent peripherals with old PCs. Typically USB WiFi cards. I'm aware of the limitations here and it's actually my daily dilemma.

ACPI is older than Presario 1245 and the laptop might be ACPI compliant, but probably just not supported properly.
