I've been debugging this and it turned out that there was an related issue with the clock setting. With that corrected this patch is not needed anymore, so you can drop it. I still see a huge number of RXADDR_NAK's after START but the ipmi_ssif driver retry logic seems to deal with that. thanks, Jan
