Rafael, Thank for the response. The common element among Logic/PCI324 users who are experiencing the kernel panics seems to be the use of external sync. Since you are using internal sync, you may be averting some trouble in this manner. Yes, iTunes also exhibits consistent kernel panics and crashes with the PCI-324 driver under external sync on my system. Apparently you have the problem with iTunes in internal sync as well. But iTunes has never gotten along well with the PCI-324 on my system, even in OS 9. 3 > > >I am using internal sync. >I will report back any thing i found after more test. i will like to >make sure i do not have any problems, Perhaps i spoke to soon. >Last night i had a crash, not running Logic but Itunes to play a test >example CD i got at the AES convention.
