Hi Martin, they indicate that you're getting transmit hangs. Means your hardware is having issues with some of the buffers it is being handed. Because the TDH and TDT noted below are not equal, it means the hardware is hung processing buffers that the driver gave to it. We need the standard bug report particulars, lspci -vv, cat /proc/interrupts, dmesg, ethtool -e eth0, and maybe output of dmidecode, etc. I'm pretty sure you know the drill.

only a little. There are so many different pieces of e1000 hardware and so few specifics in this report that I'll be able to tell you lots more when you get us the info requested.
