Here is a strange issue...installed 10.7.4 onto a D630 Nvidia, used the latest EDP, everything worked 100% perfectly with the predefined values. Used it a couple days, no issues until today when I got a "PCI Configuration Begin" hang for no reason? Booted again, it loaded fine. Trackpad was 100% ok on the login screen, but erratic once logged in. Shutdown, reboot...same issue - trackpad works fine on login screen, screws up when logged in. Ran myfix full...rebooted...trackpad is now completely unusable and is jumping all over the screen. Plugged in a USB mouse, ran EDP again, reboot...trackpad still does not work.
What's going on here??
