cannot compile kernel with ACPI support

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030922 Description of problem: When trying to recompile the kernel with acpi support, I get a number of errors, starting with the fact that include/asm/acpi.h is missing. I tried several routes to resolution, including copying selected stuff from 'official' (kernel.org) kernels, but did not find a way to make things work. It seems that an attempt was made (linux-2.4.21-acpi-update.patch) to include a newer version of acpi in the 2.4.21 kernel, but the resulting code is fairly incomplete. By the way, drivers/acpi/Config.in is not properly included in the arch/i386/config.in script so I had to do that first. I tried to find patches for the acpi version in the Redhat enterprise kernel (ACPI_VERSION 20030619), but the acpi website was cleaned up, so I could not find anything... In addition, I would like to mention that 'make xconfig' has serious problems with the crypto options. As far as I can tell, only CONFIG_CRYPTO is set after 'make xconfig', and all the other options (e.g. CONFIG_CRYPTO_HMAC) are removed from the .config file, resulting in compiler errors. 'make menuconfig' and 'make oldconfig' do work, however. Version-Release number of selected component (if applicable): kernel-source-2.4.21-4.EL and kernel-source-2.4.21-9.EL How reproducible: Always Steps to Reproduce: 1. configure acpi support (see remarks above about including drivers/acpi.Config.in and make xconfig) 2. make dep 3. make bzImage Actual Results: Error messages, starting with missing include/asm/acpi.h Expected Results: Compiled kernel Additional info: I did not make any other changes to the kernel configuration.
Self compiled kernels are not supported, and we know ACPI isn't going to work if you change it; the ACPI in the RHEL3 kernel is the ia64 variant (with patches for amd64) and not for x86.
./acpi/acconfig.h #define ACPI_CA_VERSION 0x20030619 ok but We have 2 bugs 1- /proc/acpi doesn't appears on kernel-source-2.4.21-9.EL but /boot/config-2.4.21-9.0.1.ELsmp indicates that acpi is compiled and modules like CONFIG_ACPI_AC=m CONFIG_ACPI_BATTERY=m CONFIG_ACPI_BUTTON=m CONFIG_ACPI_FAN=m CONFIG_ACPI_PROCESSOR=m CONFIG_ACPI_THERMAL=m but if I copy this to /usr/src/linux-2.4/.config and make xconfig and save the configuration all this disappears so it is a bug configuration is not correct. cat /var/log/dmesg | grep -i acpi BIOS-e820: 00000000f7fd0000 - 00000000f7fdfc00 (ACPI data) ACPI: Searched entire block, no RSDP was found.

acpi tables are parsed during boot and that's what you paste. No other acpi is present for x86, nor can be compiled in. The config snippets you paste are meaningless; # CONFIG_ACPI is not set is before teh bit you pasted and that overrules anything else. If you want to draw definite conclusions about our configs you need to run them through "make oldconfig" first. (yes I know ugly but not fixable in the 2.4 rpm context)
