--- Comment #8 from Stephen McConnell <slm at freebsd.org> ---
Hi Prateek, I'm not sure this is really the right thing to do to fix this
because it just seems that we might be covering up a larger problem where the
driver is doing something wrong. Can you attach the message file that shows all
of the output from the driver prior to the panic? I can take a look and see if
it gives me a clue as to what's going on. There are certain timing restrictions
that need to be followed when resetting the controller - maybe those
restrictions aren't being followed. Some cards are more sensitive to these
restrictions than others and, if I remember correctly, the 2308 is one of them.
In any case, I think we should dig a little deeper first before committing this
change.
