I'm a novice so if this is useful then great; if not then please ignore
My Synaptics Touchpad was working great until kernel 2.6.18 (i think)
when it suddenly stopped. By doing a diff on the source code and
commenting out the changes in turn, I found that I can get the Touchpad
working again by commenting out the following lines of the code in the
file drivers/input/serio/i8042.c.
if (wait_for_completion_timeout(&i8042_aux_irq_delivered,
msecs_to_jiffies(250)) == 0) {
/*
* AUX IRQ was never delivered so we need to flush the controller to
* get rid of the byte we put there; otherwise keyboard may not work.
*/
i8042_flush();
retval = -1;
}
It seems wait_for_completion_timeout fails and therefore the retval = -1
(i.e. fail). I do not understand why this fails or what this code does
but the Touchpad seems fine with commenting out these lines and I have
not noticed any other problems.
P.S. I'm using AMD64
