I was using the older Kona drivers when it first started. Then installed 7.0.1 and it solved it for one day. Then it happened again. I traced this second crash to the permissions on my Raid drive. Apparently Snow Leopard is not happy with the existing permissions set by 10.5.8. I unmounted the raid drive, unlocked the permissions, put them back the way they were and rebooted Snow. It worked, and so far I’m still up in FCP. Let’s hope it stays that way!
Seems like the KONA drivers and the Raid permissions were separate problems causing the same crash at start up in FCP.
