Seth & everybody
Just had a very similar problem on a brand new 17″ MBP Leopard 2.6Ghz with 4GB RAM and FCP/Studio and P2MCS and Duel Adapter.
It caused the screen to go blue and force a restart.
After upgrading to the recently released P2MCS I’ve narrowed down the problem to one of my two Duel Adapters. (BTW, I called Duel at first and the said it wasn’t the card, it was transferring over 2GB via the P2MCS; in other words, Panasonic’s software). This one particular Duel Adapter caused crashes without P2MCS or just wouldn’t recognize the P2 card (on the desktop or in the system profiler).
I have another adapter that recognizes the P2 card but won’t recognize a second card after you reject the first. The solution is I have to reboot after each card transfer.
As to my RAM, the authorized Apple Reseller says its all factory RAM (even though its not the original 2GB) so I haven’t tried to remove 2GBs yet and see how it performs.
I have tried it on a second identically configured machine with the same results.
BTW, earlier I had contacted Duel when a friend was having this problem on an older Tiger Mac laptop and Duel’s response was that their adapter works with some laptops but not with others.
So at best, I have one partially working adapter – I, like you, don’t want to accept this. Either that or I rent P2 60GB Store and just use that for transfers.
