Hmm, it looks the kernel does the right thing in case of i8042.noloop,
except that it does not work :(. Kernel triest to query the mouse but
it does not respond.

Can you try taking contents of drivers/input/serio from 2.6.25 and
copy it in .24? It will most likely compile... If that works I'm
afraid I will ahve to ask you to do git biscect to find the offending
commit.

It works. I am afraid I don't know when/if I'll be able to do the
bisecting thing :(

It would be really nice if someone has written a guide or something for
most hassle-free way of doing it on a Fedora system.

Hey again,

I finally did the bisecting. It found the cuplrit to be

    x86: assign IRQs to HPET timers
    

I tried reverting the change on the latest git with the attached patch
and my mouse and keyboard appear to be detected and working fine now.
The patch had to be stiched by hand and due to my lack of understanding
of the code might be breaking random other stuff.

FWIW the bios on this board has no knobs for HPET that I could find.

What gives?

Hmm, this is wierd and really outsize of my knowledge... Lets try copying
Ingo, Thomas and Balaji, maybe they can help us out here.

Btw, what is in your /proc/interrupts?

Hi,

Coincidentally even I hit upon this bug a couple of days ago after enabling 
HPET in my BIOS. A quick check told me that IRQ 12 which the patch assigns to 
the HPET device is used by the PS/2 mouse as well. This makes the mouse 
inactive.

I am working on this.. I am not sure if the PS/2 code is misbehaving though..

Normally IRQ12 can not be shared on X86 if PS/2 mouse is present.
If PCI side tries to grab the IRQ then ISA (legacy) side will never
see its interrupts coming.

OK. So, I need to specifically check for IRQ12 being assigned and avoid it ?

Yeah.. I think there are other legacy IRQs that should be avoided as well.
I am pretty sure Ingo would have a better idea which they are.
