Subject: Newest kernel appears to break tap feature - good starting point
	for kernel development?

Hi all,

I'm interested in getting involved in kernel development. I compiled the 
latest kernel and found that it broke the tap feature on my asus x54h 
k54l. I had a look at the way the devices were interpreted and 
/proc/bus/input/devices gave different results. This seems like it may 
be a good starting point but I'm not sure where to go from here or 
whether it's an issue with the kernel. I presume it is as switching back 
to the older kernel fixes the tapping for left click. Any advice on 
where to go from here would be greatly appreciated. Thanks.

Reza
