ide-disk not automatically loaded

[Bruno Dusausoy]

Ide-cd is not automatically loaded at boot time, but it should be.
I have a system with both SCSI and IDE drives :
- 1 SCSI hard disk (/dev/sda2 is mounted on /)
- 1 IDE hard disk
- 1 IDE cd-recorder

all these three peripherals are well detected by the kernel, as you can
see in this output (dmesg |grep [hs]d):

ide-cd should be added to /etc/modules at install time by debian-installer.
Send a copy of your /etc/modules

ide_cd is loaded, the problem with ide-disk

[Matt Zimmerman (mdz)]

They are both loaded; they can be seen in the lsmod output posted by the reporter:

> ide_generic 1664 0
> ide_cd 38276 0
> ide_core 125272 4 ide_disk,via82cxxx,ide_generic,ide_cd
                                  ^^^^^^^^
> cdrom 35872 1 ide_cd

I don't think that ide_disk can have a reference to ide_core if it isn't loaded

[Sebastien Bacher (seb128)]

I've helped him on IRC. The /dev/hda* node were missing in fact. We solved the
problem with ide_disk.

He reported after the fix, that's why "these are the ide* modules that were
automatically loaded:" doesn't like the disk module.

[Matt Zimmerman (mdz)]

OK, please try this:

sudo modprobe loop
sleep 3
sudo mount -o loop /boot/initrd-`uname -r` /mnt
cat /mnt/loadmodules
sudo umount /mnt

and send us a copy of the output

[Bruno Dusausoy (bdusauso)]

Here's the output of the command :

modprobe -k vesafb > /dev/null 2>&1
modprobe -k fbcon 2> /dev/null
modprobe -k thermal 2> /dev/null
modprobe -k fan 2> /dev/null
modprobe -k unix 2> /dev/null
modprobe -k aic7xxx
modprobe -k sd_mod

[Matt Zimmerman (mdz)]

OK, apparently ide-disk (like ide-cd) won't be automatically loaded by hotplug
etc., and so it needs to be added to /etc/modules by debian-installer.

This problem will affect any system with root on SCSI, but also an IDE hard disk.

Created an attachment (id=124)
register-module ide-disk if there are IDE devices

[Colin Watson (cjwatson)]

Patch attached. OK to upload?

[Matt Zimmerman (mdz)]

Approved

[Colin Watson (cjwatson)]

ddetect (1.03ubuntu9) warty; urgency=low

  * Register ide-disk in /etc/modules if IDE devices are present (closes:
    Warty #1400).
