I have the same problem with a MacBookPro 4,1 with the touchpad and the keyboard. Every few seconds both are going to freeze. Also I get thrown out of the user session every 5 to 10 minutes and have to lock in again. I really can't use Ubuntu on this machine any longer. I attach my dmesg results. Hope this will be fixed soon.
