Problem with Bluetooth on New Mac Pro Models

Several reports posted on Apple discussion forum (here and there) mention a problem encountered on the new Mac Pro. From time to time, without any reason nor relation to the computer status, the Mac Pro will reboot, making all unsaved data lost.
According to the first investigation, it could be a bug linked to Bluetooth appearing when peripherals are connected (such as keyboard or mouse). To prevent any problem, it is recommended ti deactivate BT or at least, not use it. However, this can not be considered as the final solution. Apple did not officially reacted to this bug, and many unfortunate Mac Pro owners are now hoping that the forthcoming Mac OS X 10.5.7 update will fix the issue.
