Yes, but keep in mind that this particular issue has to do with an ASIC whi=

So, complaining about most anything on this particular ASIC isn't going to =
accomplish much, unfortunately. The key is to a) evaluate newer ASICs on m=
ore operationally useful platforms in order to see how they handle this sor=
t of thing (EARL8 should be fine, AFAICT) and b) put the appropriate requir=
ements into RFCs so that vendors have a monetary value associated with doin=
