Hi Terry,

I'm using logging ( IOLog ) for debugging purpose. Can you provide some links/documentation for firewire debugging KEXT ? .

Please help me to solve this. Thanks in Advance.

Basically, if you want reliable communication from the kernel to user space, don't use logging, use one of the IPC facilities (sockets, IOKitUser, etc.) instead. If this is for debugging, and it's critical you don't lose data, then use the firewire debugging KEXT instead.
