How to debug and solve an OS X 10.8 kernel panic which appears quite often, sometimes twice a day?

macos macbook-pro kernel-panic

Suddenly my Mac started to have kernel panics, about 1-2 a day.

I am running latest OS X 10.8.2 on a 15-inch, Early 2011 MacBook Pro 8GB RAM with Graphics AMD Radeon HD 6750M 1024 MB, Intel SSD + HD.

I mention I did no recent hardware

Solution 1:

I'd get rid of those Citrix kexts, first of all:

com.citrix.driver.net6im    1.1.9
com.deterministicnetworks.driver.dne    1.0.18
com.deterministicnetworks.driver.dniregistry    1.0.7

A quick Google shows them to be linked with kernal panics.
