This is happening with increasing frequency, usually after waking from sleep and using Safari or iTunes (actually opening the lid to wake).

Hardware Test was fine, did Repair Permissions and Repair Disk within Disk Utility, updated my NV graphics card drivers, firmware up to date, reset SMC, etc.

    Kernel Panics can be caused by both Software issues, and Hardware issues.  Also, they can be intermittent and only occur when they feel like it.   This can make is difficult to diagnose. 


    Also, devices that we have connected to our computer, can also cause Kernel Panics.  When troubleshooting, it is a good idea to disconnect all devices, so you can rule them out.


    Running the Apple Hardware Test can help rule out Hardware issues.  If they are intermittent, running the Hardware test in "Loop mode" overnight, can be very helpful.

    10.7 - Apple Hardware Test -

    10.8 - Apple Hardware Test -


    Restart your computer, holding down the D key while the computer restarts.

    After your computer restarts, you should see the Apple Hardware Test chooser screen. If you don’t, Apple Hardware Test may not be available on your computer. You may be able to start Apple Hardware Test from the Internet. Reconnect your computer to the network, and then restart your computer while holding down both the Option and D keys.


    Many times, running the "quick" test, or the "extended" test, may not give you any error results.  Many intermittent issues, may need to have the hardware test to run in loop mode, before it detects any error, and therefore running the Apple Hardware Test in Loop Mode overnight is an excellent troubleshooting step for finding intermittent hardware problems.

    In continuous Loop Mode, the test will run continuously until a problem is found or is stopped by you, by clicking “Stop Test” or by using the Command-period keyboard shortcut. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure. Looping mode could be helpful in diagnosing a fault that may be heat related or when the fault occurs randomly.-------

    -- Insert your install disk 1 into the optical drive

    -- shut down computer

    -- restart computer holding down the D key until you see a screen with an icon of a computer appear ***NOTE if this does not boot you to the apple hardware test, try restarting computer holding down the "option" key instead, then click the right arrow to get the hardware test

    -- select English as your language and press enter

    -- The Apple Hardware Test console appears. You can choose what sort of test or tests to perform: basic or select the "Perform extended testing"

    -- press and hold down the option key and the "L" key...then select the extended test.  This will make the test go into Loop mode

    -- look over the test results and make notes of any errors that may be logged

    -- to exit out of the test, press the escape key

    Readers here can look over your panic log and may be able to give some insight. Cut and paste the text of the panic log here.

    There is a special program for that problem on that model MacBook Pro:


    TS4088- MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video



    Print out the article and take it with you and a copy of your panic log, and make an appointment at the Genius Bar.


    There is a SPECIAL diagnostic they should run Just for this problem. Do not leave until they have run the special diagnostic, as "keep it overnight" will NOT find this problem. If it fails the diagnostic, they will send it to a depot for repair, so you must have backups before you go.


    If it passes the diagnostic and is not eleigible for the repair program, you will need to remove these items before continuing to debug:

    I used to have the same kernel panic problems and crashes - often many times per day.


    I have since discovered that if I don't use Chrome, then I don't get the crashes, so I just use Firefox now.


    Having said that, I still use Chrome sometimes when I need 2 browsers for testing, and I think what I did was uninstall or take out some of the extensions.  I can't remember exactly what it was, but I have not had 1 crash since doing this.


    I hope this helps some people, I was going mad with frustration.
