I recently installed Lion on my Dell Latitude E6400 (10.7), and I'm having an annoying problem. Randomly, my keyboard and trackpad just stop working, and then I got to do a reboot to fix the issue. My specs are as follows if needed

Dell Latitude E6400
Intel Core2 Duo P8600
OSX 10.7 & Windows 8 Dual Boot
4GB DDR2 RAM
160GB HDD
BIOS Revision A32
Webcam and Fingerprint Swipe

Did you ever figure this one out? It's a problem that has plagued me since I've had this laptop (same one as you)

I've seen it written up that interrupt requests are to blame and that certain versions of AppleACPIPS2Nub.kext or ApplsPS2Controller.kext will fix this...
