While trying to write a new "OS" to my Blackberry Pearl with Windows XP SP2 through PD 3.0 5580, once it gets to a point of writing the data to the BB (It seems to read fine), it'll cause the curtain (kernel panic) in OSX Leopard 10.5.1 to pop up. It does this EVERY TIME. I realize this is probably not just a PD issue, but a problem with maybe how the Blackberry Desktop writes to the device via USB. I did not try syncing/writing to the device via bluetooth as I do not have a separate dongle to do so. Anyone seen anything like this before?
