Essentially, make fwphy_rddata() responsible for catching the error and implementing the pause(). This *should* have the same effect, unless I don't understand what I'm doing. I have eliminated the LPS check for now(see ifdef's) in fwohci_probe_phy(). If this works, I will cleanup the ifdef's before I commit.

Only question from my side, this snippet of code below does dump debug code, right? Shouldn't it be also marked as debug? The || condition hits here on the 'good' card as well as on the 'bad' card. I have no preference, but I think the less messages are more. Below the messages from both cards. (I mean this one: fwohci0: fwphy_rddata:: 0x2, retry=6) Sorry for being nitpicking, but if you feel these are necessary, fine. I'm happy having this card working and also about the knowledge I could build up. if (firewire_debug > 1 || retry >= MAX_RETRY) device_printf(sc->fc.dev, - "%s:: 0x%x loop=%d, retry=%d\n", - __func__, addr, i, retry); + "%s:: 0x%x, retry=%d\n", + __func__, addr, retry); Thanks again Sean!
