Re: crash during booting of dfly-1.1-stable (oct 27 iso from chlamydia) on Acer TM 290 while probing USB

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

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

    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.
