Debian 3.1 "missing kernel or user mode driver hw_random"...

[deref]

Hi, I am very new to installing linux, or any operating system besides windows for that matter. I am trying to load Debian 3.1 on my HP pavilion dv1432us (intel centrino) and after the install, when booting for the first time, the boot loader stops at this line: "missing kernel or user mode driver hw_random". This is all I can see on my screen:

i810_audio: can't be loaded
missing kernel or user mode driver i810_audio
<3>i810_rng: RNG not detected
insmod: /lib/modules/2.4.27-386/kernel/drivers/char/i810_rng.o: init_module: No such device
insmod: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
insmod: /lib/modules/2.4.27-2-386/kernel/drivers/char/i810_rng.o: insmod i810_rng failed
i810_rng: can't be loaded
missing kernel or user mode driver i810_rng
hw_random: RNG not detected
insmod: /lib/modules/2.4.27-386/kernel/drivers/char/hw_random.o: init_module: No such device
insmod: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
insmod: /lib/modules/2.4.27-2-386/kernel/drivers/char/hw_random.o: insmod hw_random failed
hw_random: can't be loaded
missing kernel or user mode driver hw_random


Now, I have been doing some reading and that hw_random has something to do with a hardware random number gen (which aparently the centrio does not have). I am a programmer and know that hw_random.o is some type of link library. But because I don't really know much about linux, I have no idea how to stop this from loading !

If anyone can help me out that would be awesome! I just bought this computer with the hopes of loading linux on it and getting to know it better, but this problem I'm having is really throwing a wrench in the gears!

Thanks to all that attempt to help

U may benefit from using ist install cd from Etch wc has newer kernel or upgrade ur Sarge install to use Etch kernel-called linux-image 2.6.12 by adding Etch sites to apt sources list. Sarge has 2.6.8 kernel available i think. The 2.6.14-x is avail in sid. Maybe google search will show u how others installed debian on similar pc/mob. Good luck.

hw_random has nothing to do with your CPU, it is purely related to the motherboard you are using. Yours doesn't have a hardware random number generator.

On a laptop, you don't have much chance of getting it to work with a 2.4 kernel. You could always reinstall Debian using this at the prompt:

linux26

or

expert26

which is the one I use.

With a 2.4 kernel, it's better to set your BIOS to "plug & play OS = false", as for a 2.6 kernel "plug % play OS = true" works much better.

Try to load in "recovery mode" if you can and then install a 2.6 kernel; see if it works better for you.

Normally the best thing to do is to use a custom compiled kernel, on any laptop.

Thank you for your replies!

I tried what was suggested and came to no solution... So, I did more research and finally found this post by Philip Schwartz:

"Nate,

What type of laptop? I have an HP dv1000 series laptop that I get the same
problem. The seg Fault is with S36discover. I am in the process of typing
a walkthrough to get around it.

The problem is not just discover, it is also hotplug. Hotplug hangs on the
older usbcore module in the install kernels on some laptops.


Here is a break down:

1.> Install Sarge normally, either 2.4 or 2.6 kernel.

2.> on the first boot change grub or lilo options to include "init=/bin/sh"
After about 30 seconds you will be given a bash shell

3.> remount root partition. "mount -o rw,remount /"

4.> Either uninstall discover and hotplug or move init scripts.

a.> uninstall
"dpkg -P discover1; dpkg -P hotplug"

b.> move init scripts
"mv /etc/rcS.d/S36discover /tmp/"
"mv /etc/rcS.d/S40hotplug /tmp/"

5.> remount root partition ro. "mount -o ro,remount /"

6.> Reboot (you will have to hit the reset button)

7.> The machine will now start normally. go through the base-config to
setup the apt repos and then stop.

8.> use apt to install latest discover and hotplug

"apt-get update; apt-get install discover2 hotplug"

9.> reboot system. "shutdown -r now"

10.> the system will then come up normally, rerun base-config and finish
setting up your system.

I have tested this on 2 dv1000's, 3 dv4000's, an r3000z, and a v2000. It
should work on any system that hangs in discover on boot.

Hit me with an e-mail if you have any questions.

Thanks to his post, this problem is solved for me! I hope this will help others if they are experiencing the same problem

deref , i think u can blacklist that i820 thing in hotplug file to stop the error message. Good luck.

Sorry for typo shd be i810 nto i820. Tried to edit but no go.

Hello everyone,

I'me trying to install Debian on my laptop and I'm experiencing the same problem.

I tried to modify the grub options as said above but I can't figure out how to do it from the command line.
Which means I'm stuck at stage 2....
I tried to type :
kernel /boot/vmlinuz-2.6.8-2-386 root=/dev/hda1 init=/bin/sh
then
boot

but no good, I get the same problem.

Could someone give me a clue?

Thanks in advance.

Teuk.

[profchiken]

edit the same line only with:

kernel /boot/vmlinuz-2.6.8-2-386 root=/dev/hda1 ro init=bin/sh

thank you so much for this thread, it is a lifesaver.
