[Bug 577671] Re: mouse and keyboard don't work with motherboard ASUS p4s800

[Anthony Bodle]

I also have the same problem with an Asus P4S800 mobo when just running
off a 10.04 LTS CD, that I burned myself.

My keyboard and mouse nearly always freeze by the time the desktop comes
up.  On the rare occasions they are not frozen immediately, when I touch
the keyboard I get the "stuck Key" effect in that the key I tapped once
produces the same character all the way across the input field, and then
the system hangs with frozen mouse and keyboard.  Of course I cannot
look into the logs to see what has happened as I have no control over
the system by then.

A bit of background if it will help.  I had experimented with an old
8.04 CD from Canonical, and on all my systems it worked fine just
running off the CD.  So I downloaded the recent 10.04 and burned a CD
with high expectations and tried running it off the CD on the same
systems.

It works fine on an ancient Compaq P2 
It fails on an Asus A7V600-X / Nvidia GeForce giving me a screen full of fine grained coloured specks

It fails on my test machine an Asus P4S800 / Nvidia Geforce with the symptoms described in para 2. 
On this test machine I tried the "Troubleshooting ACPI and APIC Problems" set out in Documentation / ReschedulingInterupts with the following results.

acpi=off runs ok but one cpu only
nolapic  runs ok but one cpu only
noapic  runs ok both cpus
acpi=noirq runs ok both cpus 

I then proceeded to install it on my hard disk using the acpi=noirq
option in the installer, dual boot with Windows that was already on the
machine.  The install ran ok, on reboot I get the OS selection screen,
but when I choose Ubuntu it boots up and I am back with frozen mouse and
keyboard.  So presumably I need to add an option to the boot loader as a
workaround?

Given my early success with 8.04 I was not expecting this much
difficulty.  Windows works fine on all these machines.

Let me know if I can help in any way.
