I don't know if this is related, but I updated an amd64 zfs machine with several em cards from 7.2 to 8-stable yesterday. First it worked fine after booting, but this morning, at least three of the five em interfaces did not do much anymore. You could revive them for some seconds with ifconfig down/up, but they always ceased functioning soon after that (within seconds). During debugging (up/down, load/unload if_em etc.) I saw the same error message as above at some point. I finally gave up and rebooted the machine. For now, everything appears to be back to normal (but for how long?). JV> Not sure why this results in a lockup, but try and increase JV> kern.ipc.nmbclusters. I just did that, just to make sure. cu Gerrit
