Building a new kernel

[David HM Spector]

OK.. I'm stumped. Building working kernels and initial ramdisks under RedHat has always been a bit of a black art. However under RH8 no matter what I do I get a kernel panic (unable to open root fs) when I try to run my custom system.

The kernel I am using is the latest from kernel.org (2.4.20) with the probe all SCSI LUNs turned to support a tape autoloader I want to use on this system and most everything else enabled as a module. I tried to recompile the 2.4.18-18.8.0 kernel sources using RedHat's config file but got zillions of errors ralating to network devices, and God knows what else.

For the 2.4.20 kernel, the make dep;make vmlinux; make modules;make modules_install and then make install all execute without error.

I've tried using rdev to tell the /boot/vmlinuz-2.4.20-custom boot image what disk its on all to no avail (although when I ask it with rdev what its boot disk is I get the correct answer -- sda5 in my case [sda1 is /boot]..)

Has anyone had success building a custom kernel under RH8..?
