My trusty Mac Mini (late 2009 model) has been running 24 hours since I bought it in late 2009 and had never had a kernel panic until the last couple of days. The only system change in the last 6 months, apart from Apple updates, was the installation of the FTDI drivers that came with MPIDE and of course MPIDE.

As far as I can tell, disconnecting the UNO32 while the system is in sleep mode causes the FTDI drivers to panic the kernel.

I now try to remember not to do this :)

Do the kernel panics stop if you use the version of FTDI drivers from FTDI?

If the problem is resolved with this update we can add newer drivers to the distribution.

Just downloaded the 64 bit FTDI driver. Will install and let you know.

The version shipped with MPIDE was 2_2_14. The version from the FTDI website is 2_2_16.

The only change in behaviour is that while the _14 version crashes the machine completely when unplugging during sleep, the _16 version gives me an Apple dialog box in 6 languages telling me the system needs to shutdown and to hold down the power button until the machine turns off :-) No great progress!
