Ht everyone,

I recently decided to leave my older version of mandrake distribusion of linux and try something that at the house were I live is totally new (Ubunto).

So I got the cd and started to install the Ubunto... funny thing is that the process goes well untill I reboot the pc(ASUS A6VM), it starts to load untill it gets to this part:

starting network [ok]
starting hot(somthing) ... _

and it just stops...

I tryed doing something, it isin't blocked cause I did :
ctrl+alt+f1 to go to the tty1 and it goes there, and there it simply says:

rng not detected


If anybody could help me, you don't even imagine how much I'd apreciate...

A concise diagnostic checklist and safe fixes for an Ubuntu install that appears to finish but then stops late in the boot sequence (the machine shows a hotplug/”hot…” service stall and an informational “rng not detected” message).

The single “rng not detected” line normally means no hardware random-number device was found and rarely causes a full hang by itself. The real blocker is often a user-space hotplug/udev process waiting on hardware or a kernel/hardware interaction (ACPI, IRQ, PCMCIA, modem, internal card) on that laptop model. ’s suggestion to stop the normal boot and run in a minimal environment is the right first diagnostic step; ’s point about removing extra peripherals also applies for laptops with PCMCIA/USB cards, and ’s alternate-install suggestion is a reasonable fallback if hardware compatibility is persistent.

Key diagnostic steps (use recovery mode, GRUB edit or a Live CD to get a root shell):

# look at kernel messages and boot logs
dmesg | tail -n 100
tail -n 200 /var/log/syslog
grep -i hotplug /var/log/syslog
lsmod | grep rng

If the logs implicate the hotplug/udev path, temporarily disable that startup script from a rescue shell or chroot (safe method shown here):

sudo mv /etc/init.d/hotplug /etc/init.d/hotplug.disabled
sudo update-rc.d -f hotplug remove
# to restore later:
# sudo mv /etc/init.d/hotplug.disabled /etc/init.d/hotplug
# sudo update-rc.d hotplug defaults

Other useful boot-time tests: remove quiet splash from the kernel line to see all messages, and try kernel parameters one at a time (acpi=off, noapic, nolapic, nomodeset) to isolate ACPI/IRQ/video problems. If a Live CD boots fine, chroot into the installed system and run update-initramfs -u -k all and update-grub before retrying. Preserve a separate /home partition before reinstalling if switching distros.

Have you got any peripherals attached, like USB printers, network adapters, or hard drives? When you're installing, just install with the network cable, keyboard, mouse, and Monitor attached-- that helps with a lot of boot issues like what you've described.

I'm using a laptop (asus a6vm) and there are no peripherals atached exept those that come in the computer...

Thank for responding to my problem...

Suggestion for a different 1-CD installation to try: PCLinuxOS. You can check it out through the link at . I have been using PCLinuxOS at work without issues on NVIDIA (not as new as yours, though).

My favourite is still FC5 (4 CDs, typically). That's my home machine, running on a Shuttle SB61G2V4... so cool and so quiet ... assembled in 60 minutes...great cables and great installation manual .. Oops ... I am off topic!

Try Ubuntu 6, perhaps, when it comes out (I will). No matter what distro you start with, keep one HDD partition stable (E.g. /home) so that you can maintain it intact no matter how you change distros by always doing a custom partition setup during install. Under home, I have myself, JDK, (linked to from the one in /etc), Mplayer + codecs, BOINC ... you get the idea. Hope you find the idea useful.

Best wishes.

The service that it was most likely trying to start (only one that I'm aware of that starts with hot*) is the hotswap service, this is typically used for hotswap hard disks, or USB devices that can be removed while the machine is running. I'm not sure how familiar you are with unix/linux, but have you attempted to get the machine to boot into single user mode?

To do this, you will just need to add the word 'single' after the kernel line in the grub entry. You can modify this on boot by pressing 'e' or 'a' when the kernel list shows up.

If the machine boots into single user mode, you should be able to disable specific services (ie. hotswap) and reboot, and verify that this is indeed actually the cause of the issue you are experiencing.
