Do you have Local APIC or IO APIC (not the same as ACPI which is related to power management) enabled in the kernel? If you have, APM won't work and the symptoms will be really strange. The machine will behave like you fed it something inappropriate. Look at this thread: http://lists.debian.org/debian-laptop/2002/debian-laptop-200201/msg00191.html and this message in particular: http://lists.debian.org/debian-laptop/2002/debian-laptop-200201/msg00227.html I do this: - I then take the kernel-source package for the same kernel version, and untar it in /usr/src. - I take the precompiled debian kernel (2.4.18-686) and grab its config file from /boot/config-2.4.18-686 and copy that config to /usr/src/kernel-.../ with the name .config. - I then run make menuconfig and go to "Processor type and features" and answer N to "Local APIC support on uniprocessors". Then I exit and save the config. I change nothing else. - I then run "make-kpkg --initrd --revision inspiron.x.x kernel_image" where x.x is some version number I make up. After a while I get a deb package in /usr/src that contains a very nice kernel and every module I could wish for. (Which is good when you have, say pcmcia cards of yet undefined models that you might have to use. The module will be there if needed.) dpkg --install'ing this package (plus a little tweking with symlinks in some cases) is all there's left after that. Note: - It will be an initrd kernel, which means you have to configure your bootloader to use initrd. It's really easy. The man page for lilo explains quite a lot. - You need the kernel-package package for make-kpkg and some other packages (at least cramfs-tools if I recall correctly) to accomplish the above.
