Here is my cheat-sheet for recompiling the linux kernel.

1. Install the kernel source "rpm -ivh kernel-source-<kernel_version>.i386.rpm" ".
2. cd /usr/src/linux-2.4 (or what ever version the /usr/src/linux-#.# dir is)
3. Run 'make mrproper'
4. Run 'make oldconfig'
5. Run 'TERM=vt100'
6. Run 'export TERM'
7. Run 'make menuconfig'. Change whatever you want to change at this point.
8. Run 'make dep'
9. Run 'make clean'
10. vi Makefile, update the version,call it something logical.
11. Run 'make bzImage'
12. Run 'make modules'
13. Run 'make modules_install'
14. Run 'make install'
15. Run 'mkinitrd /boot/initrd-<custom_version>.img <kernel version>' like this:
mkinitrd /boot/initrd-2.4.9-e.5LUN.img 2.4.9-e.5smp
16. (Do this only if you are using lilo) vi /etc/lilo.conf, create a new entry like this:

image=/boot/vmlinuz-2.4.20-8-custom
label=2.4.20-8-custom
initrd=/boot/initrd-2.4.20-8-custom.img
read-only
append="root=LABEL=/

Be sure to replace the version info with the custom version you created.
17. (Do this only if you are using lilo) If you are using lilo, run 'lilo'
18. (Do this only if you are using grub) vi /etc/grub.conf, create a new entry like this:

title Red Hat Linux (2.4.20-8-custom)
root (hd0,0)
kernel /boot/vmlinuz-2.4.20-8-custom ro root=LABEL=/
initrd /boot/initrd-2.4.20-8-custom.img

Be sure to replace the version info with the custom version you created. Be sure to have the correct root location. It may be easiest to copy an existing section and just replace the stuff you changed.
19. reboot, you should see the new version in the boot list.

To troubleshoot the specific hotplug issue you are having I would possibly try a different approach:

1. run 'depmod -a'
2. run 'modprobe hotplug'
3. run step 15 from above.

This may give you more info about why you are having problems specific to hotplug. Once you figure out the hotplug problems, then go back to the above procedure.

linux-version

LINUX-VERSION(1)					      General Commands Manual						  LINUX-VERSION(1)

NAME

       linux-version - operate on Linux kernel version strings

SYNOPSIS

       linux-version compare VERSION1 OP VERSION2

       linux-version sort [--reverse] [VERSION1 VERSION2 ...]

       linux-version list [--paths]

DESCRIPTION

       linux-version operates on Linux kernel version strings as reported by uname -r and used in file and directory names.  These version strings
       do not follow the same rules as Debian package version strings and should not be compared as such or as arbitrary strings.

       compare VERSION1 OP VERSION2
	      Compare version strings, where OP is a binary operator. linux-version returns success (zero result) if the  specified  condition	is
	      satisfied, and failure (nonzero result) otherwise.  The valid operators are: lt le eq ne ge gt

       sort [--reverse] [VERSION1 VERSION2 ...]
	      Sort the given version strings and print them in order from lowest to highest.  If the --reverse option is used, print them in order
	      from highest to lowest.

	      If no version strings are given as arguments, the version strings will instead be read from standard input, one per line.  They  may
	      be suffixed by arbitrary text after a space, which will be included in the output.  This means that, for example:

	      linux-version list --paths | linux-version sort --reverse

	      will list the installed versions and corresponding paths in order from highest to lowest version.

       list [--paths]
	      List kernel versions installed in the customary location.  If the --paths option, show the corresponding path for each version.
