    Random Kernal Panics in Lion with MC 5.5

    Hello all,

     

    I am having some bad kernal panics when using MC 5.5 in Lion 10.7.3. Most of the time they occur in the midst of capturing from tape, but sometimes the Avid may just be sitting on it's own or I had an instance where files were just be transferred to an ISIS partition outside of the Avid.

     

    Currently I have done all of the following:

    -Pulled all cards and only had the DX card in (Slot 4)

    -Digitized to the local drive

    -Done a clean install of the OS

    -Upgraded and downgraded between versions 5.5.3.3 and 5.5.3.4

    -Started new projects and bins in different locations

    -Digitized at various different resolutions

    I am at a complet loss right now. These are all brand new Mac Pros running Westmere 12 cores and 16GB Ram.

    I read also about the kernal toggle but upon looking at the system reports, none of the 64-bit kernal is enabled on the computers.

    We cannot upgrade to 6.0 because we are mingling older systems not supported by the version

    Anybody have any advice. I am trying to get Avid support, but it has been a slow process.

    Kernel panics can be the result of a hardware fault.  If it's happening on multiple macines, run the Apple hardware test that came on your install DVDs (or off the boot disk if you haven't reformatted it) and see if the memory passes the extended test.  You could also try swapping the DX card between machines to see if the problem follows the card.

    Do you have some machines that work and others that don't?  Are the faults happening on multiple machines with the same configuration or is it isolated?

    Did they ever work or has this problem been evident from the first install?

    I did run a hardware test on one machine overnight. I came in this morning and it did give me a error code:

     

    4SNS/1/4000000: Ip6m - 0.898

     

    From what I read it is "Sensor Curent" then "Current" and "Power Supply" related errors. I did run this test with everything disconnected but I kept the DX PCie card in the slot during the testing. Do I need to redo without the card in it?

    There is no point swapping the cards, because it seems to be happening on multiple machiens.

    So far I have tested about 4 machines extensively and they all are having similar kernal attacks as I described before.

    They all have the same configuration, the results don't seem to be isolated to a single machine

    They have all been problematic since I received these machines and first installed them

    I'd investigate the memory.... what brand, how is it installed, etc, etc.  In the past, most kernal panics for me have ended up being memory related.

    We had the stock memory in most of the machines either built with 6GB (2010 model) or 12GB (2012 model) depending on the model year. We then received 4GB memory kits from Crucial. I put one kit in each of the machines. I put them in slots 2 and 5. I did not remove any of the stock memory.

    Should I not be mixing and matching the stock memory if I am expanding with different kits?

    It's hard to say for sure.... but it's easy to test.  I've certainly had memory over the years that didn't play nice together.  Also the RAM needs to be installed in a certain order and in matching pairs.  It's somewhat confusing.

     

    Go here and scroll to the bottom to where they actually show you the pic of the memory cards and what slots to use and in what order.

    I pulled the additional RAM sticks and reconfigured the slot configuration on the board to match what this article says. I uninstalled MC and removed all the cards and ran the diagnostic again.

    It still continues to give me that hardware fault error, even with just the stock memory

    OK.... so what other common variables do these machines have?  Anything..... USB multipliers, etc.... anything else?

    Do those machines have Software Activation or Dongles?  If not a dongle can you try starting up by holding down the 3 and 2 keys and testing again?
