I'm also having issues when pulling stuff from my main system via TFTP sometimes. This is manifesting by _lots_ of timeouts. The problem in this case is some weirdness in e1000e in my system, after I force-switch the main system to 100baseT (using ethtool -s eth0 speed 100 duplex full), I no longer get timeouts (even after I force-switch it back to 1000baseT later). But I suspect this is some network issue on my end. Best regards, Marek Vasut
