Have been getting regular kernal panics since upgrading to 10.7.4. Ran applejack and got the following message:

FireWire GUID ffffffffffffffff is invalid!

Hoping this is my problem. Any advice?

MacBook Pro, Mac OS X (10.7.4)

    Launch the Console application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

     

    Select the most recent panic log under System Diagnostic Reports. Post the entire contents — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post shutdownStall, spin, or hang reports.

    The message from kernel

    FireWire GUID ffffffffffffffff is invalid!

    may be seen sometimes with a problematic device on FireWire, sometimes without a device on that bus.

     

    In my case I see the message if I allow sleep of both (a) hard disks and (b) the computer (MacBookPro5,2), then wake the computer – with a LaCie hard disk drive, on FireWire, that is known to be problematic. So I don't seek help, this is just an example of an environment where the message may be seen.

     

    In another person's case (details of which I can not divulge) there's a Thunderbolt interface to a display with a FireWire port, and no device on FireWire.

    That's from a .crash file.

     

    Look instead for the kernel panic reports. In Finder, go to

     

    /Library/Logs/DiagnosticReports

     

    – then work with file names that begin with

     

    Kernel_
