Subject: Re: bnx2x machine check in bnx2x_ack_int()

Hi Bjon,

My sincere apologize for the late response. When searching the mailing
list to see if I accidentally missed your reply, I have come to realize
that my response was never sent (problem with my email client).

I see that you are using two 57710 chips. What kind of board are you
using (which PHY)?

If you set the right FW on the board, do you still see the problem? I'm
asking to determine if this is a problem specific to the "no FW" case or
general issue with this configuration

Unfortunately, with the 57711 Mezzanine on the IA64 blade that I have, I
cannot reproduce this failure, so I will probably need more information.
Can you please send me the nvram content?

Thanks,
