Kernel Panics with Decklink Extreme
For the past 3 weeks I’ve had the same problem. When playing back a clip in FCP right before it starts to play I get the lovely kernal panic that we all love so dearly. This happens only when I am outputting via the Decklink Extereme PCIe card on my MacPro. Media is all spinning off a FW800 raid as 10 bit uncompressed. 5 GB of DDR2 ram. The video is output via RGB compenent to my monitor. I have the most updated versions of every peice of software and when the computer goes down I see the last thing before the crash is a reference to the blackmagic driver 5.7.2.
The card works perfectly in Motion and in Photoshop. Just the problem with playback in FCP. Does anybody else out there have any ideas or suggestions. I think I have tried everything. Reinstalled everything twice (new user accounts). Again the problem is only on playback in FCP (I can step through the video fine, just not watch in real time). For now I am having to use apple cinema display for output.
PLEASE HELP!

Hi Chadwick,
Please reduce your RAM to 3GB and then see if the kernel panic goes away. The DeckLink 5.7.2 Readme file includes the following statement:
Currently all DeckLink standard definition cards are limited to 3 GB of memory, however this will be updated in a forthcoming software update.
I’m guessing that reducing the RAM for use with the standard definition card will be the solution to this problem. Please let me know if it continues when only running 2 or 3 GB of RAM.

Hi,
please also check if all your ramm dimm’s are of the same type and frequency. mixing them also cause these kind of problems.sameer

Thanks Luke – yeah reducing my ram fixed my problem (just longer renders in other apps now). When do you foresee a new driver available so I can use all 5 gigs of DDR-2 I purchased?

I had the same problem on my Mac Pro. I moved the DeclLink card from PCIe slot3 to PCIe slot 4 and the problem went away. BM mentions on their system requirements page that you try this if you have problems, but doesn’t specify that the card MUST be in slot 4. ?. Whatever works eh.
