Hi Andrea's,
Thanks for the initial response.
My Kext is a pure generic kernel extension -- not an IOKit kext.
My Kext tries to capture file system events and send the notification to user process and also tries to provide responses to ioctl command (which are specific to my application).
Kext Unload doesn't happen on PPC Mac's ( TIger as well as Leopard ) - but its happening every time only on Intel Mac(Tiger & Leopard). Why does my kext unload gets called automatically. Is there any code which i need to handle for the Intel Mac's ?
Please help me to solve the problem.
TIA,
JanakiRam.

What is your kext doing? What does it make it load initially?
My pure guess is that MacOS X wakes up and doesn't see the physical device anymore and thus IOKit unloads the driver. Maybe your hardware device takes more time to wake up than the kernel so a unload/reload scenario would be happening.
