FYI,
If you have recently ran apt-get upgrade or dist-upgrade and then tried to compile and install a 2.6.4 kernel, you *may* encounter failure to successfully install the newest kernel from a knoppix/debian installed system.
Problem:
Installing the new 2.6.x kernel reports 2 modules missing; ide-disk, and ata-piix. Repeated attempts will stop at this point.
Solution:
This isn't for the faint of heart, you need to open a console as root, cd /usr/sbin, and edit the mkinitrd file. There is a section that points to these two files which need to be deleted and then saved. Re-run the dpkg -i command to install the kernel and it will be successful.
For those of you who do not want to edit the mkinitrd file, here is the full file itself, just copy and paste into the faulty mkinitrd file as root. Make sure you make a backup first and save it for future reference. Overwrite the mkinitrd file with this code:
#!/bin/sh

HTH,

If you have recently ran apt-get upgrade or dist-upgrade and then tried to compile and install a 2.6.4 kernel, you *may* encounter failure to successfully install the newest kernel from a knoppix/debian installed system.
Problem:
Installing the new 2.6.x kernel reports 2 modules missing; ide-disk, and ata-piix. Repeated attempts will stop at this point.
Solution:
This isn't for the faint of heart, you need to open a console as root, cd /usr/sbin, and edit the mkinitrd file. There is a section that points to these two files which need to be deleted and then saved. Re-run the dpkg -i command to install the kernel and it will be successful.
For those of you who do not want to edit the mkinitrd file, here is the full file itself, just copy and paste into the faulty mkinitrd file as root. Make sure you make a backup first and save it for future reference. Overwrite the mkinitrd file with this code:
#!/bin/sh
#
# mkinitrd - make an initrd image
