Have you recently installed any new RAM (or made any other hardware changes).

Are you plugging in or unplugging any USB or Firewire devices when this happens?

Are you using a dial-up modem?

Hi. Thanks.

I am not using any USB devices when that happens and my modem is not in use at all, I connect to the internet with airport.
I have changed the hard dive but it works OK and it has been more than 2 months that I changed it and just now I am having the panics.
I have run the diagnostics (extended) and it seams that everything is OK hardware wise.

The panics have been appearing when either when I open apps or just before restarting or shutting down.

Cheers hope this helps, do you find anything familiar in the log?
