I had a very rapid response from MOTU regarding kernel panics.
I quote:
******
Can I get a little information on your system?
Mac model and processor speed -
OS X version -
Card Version - this is found on the label on the bottom of the card
RAM configuration - how much and how it's configured(ie 1 gig via 512 x
1/256 x 2 etc)
A few things to check:
Is the MOTUPCIAudio.kext inside of System->Library->Extensions?
Do a search for the MOTUPCIAudio.kext to make sure that there is only
one installed in the system.
Open Terminal and paste in the following:
sudo rm -R /System/Library/Extensions/MOTUPCIAudio.kext
and Press Return
You will be prompted for your password. Enter it and hit return. Quit
Terminal and run the MOTU PCI Audio Installer, select Uninstall from
the Install dialog box. After complete, restart the machine. Then run
the installer file again and restart.
If you continue to get a kernel panic, let me know. Make sure to put
ATTN: Jon in the subject line.

Anyway, I invited this Jon guy to come over here and talk about it
I don't have a double extension as he mentioned, and I guess this is something MOTU are aware of due to the speedy response.
