Duel System Adapter + MacBook Pro = Kernel Panic?

Question

I was on set for a P2 shoot as the "P2 Dumper" a few days ago. Cards where all ranges of sizes (4GB to 32GB) offloaded to my MacBook Pro via a Duel Systems Adapter. The MBP was purchased brand new on Sunday (2.5 Ghz 15"; so 10.5.2 & QT 7.4.1 were pre-installed). I installed the Panasonic P2 Mac utilities (P2PCCard Install, P2 Formatter, etc) as well as P2CMS after I installed FCS 2 and updated to FCP 6.0.2.
Now, I'd read that the Duel System Adapter usually required a system restart before you could typically read the card. What I didn't expect was the kernel panic I kept experiencing whenever I inserted a P2 card into the adapter after a period of inactivity.
What I mean to say is, when offloading one card after another (usually in the span of 20 minutes), I never got a kernel panic. But when I had to start the process from scratch - meaning I hadn't offloaded a card in 30+ minutes - inserting a card would guarantee a kernel panic.
This is with the adapter continually plugged in. Was that my mistake? Is it required to eject the adaptor when done with a series of cards, then reinsert it (and restart) when beginning the offloading process again?
I'm guessing this is just me overlooking an understood aspect of the workflow, rather than me bumping into some brand new issue...

Hey Hanumang,
I too am having kernel panics using the latest (Penryn, Feb refresh) Macbook Pro and a duel system adapter. My kernel panics have been occuring during ingest/export when using P2CMS. Here is my set up:
Penryn MBP
OSX 10.5.2
Quicktime 7.4.5
FCP 5.1.4
P2CMS 1.1.9 (latest)
I have all the necessary drivers (no additional drivers are needed with Leopard and the Duel Adapter).
My kernel panics are happening when I am ingesting/exporting using P2CMS after about 1gb of transfer. Here is my exact workflow:
Shoot 720/24pn on an HVX to an 8gb card.
Write protect 8gb card.
While off, insert Duel Adapter to MBP.
Boot MBP and insert P2 card into Duel Adapter, P2 card mounts fine.
Launch P2CMS
Select P2 card as the source
Select all clips -> right click -> export to MBP hard drive.
After about 1gb of transfer, I get a kernel panic, 5 times out of 5.
Notes: No issues with the Duel Adapter when using a drag and drop method. No issues using above workflow using P2CMS and using the HVX and firewire to mount P2 cards. I only get kernel panics when using the Duel Adapter and P2CMS to ingest footage.
