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.
