Re: touchpad wakes up the kernel too often

[stephane <hasard@gmail.com>]

May I ask you how many wakeups per second your touchad causes? Mine
causes 200 which seems a lot and the source
(/drivers/input/mouse/appletouch.c) mentions "avoid waking the kernel
up several hundred times a second."

Thanks

Stephane
