Well, unexpected packet recieved means (I think) the packet that was sent
internally was not expected to be recieved from within a device process.
Something new in 1.3 I guess. Playing with packets has always been a dangerous
business.
265F48F1 is the memory adress the guru  happened at.
(hex). If you have another Amiga hooked up to your crashed Amiga's Serial Port
via null modem, you can then enter the debug mode on the crashed Amiga and
check the system out for the problem.
