I have a Dell E1505 (6400) with a Core Duo processor. I have Snow Leopard 10.6.4 installed and have the VoodooTSCSync kext installed. I can consistently get a Kernel Panic when I start Activity Monitor or even the "top" utility in a terminal shell. I would post a Kernel Panic backtrace log here. However, I am not seeing any Kernel Panic logs in /Library/Logs/. There is no CrashReporter/ or DiagnosticReports/ directory in that directory. Am I looking in the wrong place?
Interestingly enough, under my previous Snow Leopard installation (I had to reinstall due to problems when setting up triple-booting), I could (sometimes) start Activity Monitor without causing a Kernel Panic.
