    Is this something that worked with DFly before that date and suddenly
    stopped working?  Or has it never worked?
never tried that before.

    At the db> prompt try giving the trace command different offsets relative
    to the 'stack pointer'.  so, e.g. in this crash the stack pointer is
    0xc062db10 so you would want to try giving the trace command 
    0xc062db14, 0xc062db18, 0xc062db1c, 0xc062db20, etc.  See if you can get
    find an offset that generates a good trace.




always crashes the same, but with verbose booting it gives another line after uhci0 line:
:Without ACPI it stops after probing USB:
