I have a dell inspiron 5100 and have been trying in vain to get the power management to work. I have downloaded the 2.4.22 sources applied the dsdt patch and created a hex file with the Dell-custom.......asl patch etc.

My problem is when I try to compile the kernel I get the following error.

make[3]: Entering directory `/usr/src/linux-2.4.22/drivers/acpi'

I have tried everything I can think of, including deleting the sources and starting from scratch several times. Any help would be appriciated

try it using your current kernel configuration

that is what I have been doing, I have also tried using the "safe" config that redhat 9 generated during install.

Well, I got the battery monitor working which is mainly what I was concerned about, I will move on to suspend and sleep later.

Just a note I never got the patching of the kernel with the dsdt patch to work successfully, I ended up finding another post here that had a link to a different sert of patches and that worked.
