Actually, it now finds the task and tries to do error handling for
it ... so we've now uncovered bugs in the error handler.  It may not
look like it, but this is actually progress.  Although, I'm afraid it's
going to be a bit like peeling an onion: every time one error gets
fixed, you just get to the next layer of errors.

The firmware upgrade tools are usually vendor specific, though because
the format of the firmware file is vendor specific.  Could you just put
it in a dell box to upgrade?
