I would look at the various settings that ethtool controllers. You might dump all of the ethtool settings when it is working, and then do the same when it is not working and see if there is a setting. I have seen before were OS'es seem to assume some state in the nic cards (clean powerup) and when that state is not right(reboot with power up) they don't set set and either it does not work or it fails in weird ways. the ethtool -t offline is often useful because it seems to reset the nic, it is useful when the "reset" is not supported or does not work. There is also a reset. The biggest issue with the ethtool settings is not all nic cards support and/or have code for all of the functions so it is somewhat trial and error.
