shutdown hang in 8.10

[Ewan the moomintroll]

Hi there,

a few weeks ago I installed ubuntu 8.04 and was very happy with it as my first Linux experience. The only problem was that when I shut down it the orange bar would go completely black and then hang, i had to hold down the of button to switch of.
I did a lot of googling and found that the problem has no end of potential fixes, but none of the ones i could find fixed the problem for me so i gave up and waited for ubuntu 8.10 to be released in hope that it would fix it.
It hasn't.
can anyone help?

I've also noticed that restarting my computer works fine so it's just shutting down.
My motherboard is a epox 8k5a3+.

I should probably say that i edited "menu.lst" because of several fixes (I can't remember what I did exactly).
When i installed 8.10 it asked me if i wanted to replace "menu.lts" and i said no because i wasn't sure what it meant.

just noticed that system monitor says I'm using linux kernel 2.6.24-21-generic, despite it saying that intrepid ibex should have 2.6.27 in the release notes. I should definitely fix that, so any help on how to do so would be great.

Edit: this problem is fixed, but problem persists.

Adding "pci=conf1" as a boot option gets rid of the error msges. I dont know how to make a boot option permanent though.

I am encountering a problem that sounds similar to the OP's on an Acer Travelmate 4000.

My system very consistently will not shut down. The splash screen will pop up, the orange bar will crank all the way down until it is black, then I will hear the harddrive and the CPU fan turn off. It then sits there for a moment, and suddenly the splash screen goes away, and in the upper left hand corner of the screen it says:

acpid: exiting



I've tried a number of suggested fixes. I've modified my stop rule in the /etc/init.d/alsa-utils to look like this:

stop)
ifconfig wlan0 down
ifconfig eth1 down
ifconfig eth0 down
EXITSTATUS=0
TARGET_CARD="$2"
ect ect..

(bolded portions are my additions)

I've also edited my grub menu file's default rule: /boot/grub/menu.lst:

kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=6419e63e-a1c0-49f4-abef-f3bb1d15ec6f ro quiet splash acpi=force pci=noacpi

(the bolded portions are my addition).

It may be important to note that NONE of the changes made to either of these files had any effect what-so-ever.

With the grub file, I attempted both "acpi=force" and "pci=noacpi" separately. No dice.

With regard to the alsa-utils, I attempted every possible combination of those 3 lines, including all of them alone. No dice there either.

In my terminal, the command: sudo ifconfig wlan0 down has no effect. eth1 is my wireless card. I'm not sure if this means anything.

I have backups of all files, and know my changes, so I can unmake them easily enough if they hurt anything.

Any suggestions at all would be greatly appreciated.
