The problem does not occur, when I boot up the system without the
hypervisor. So I still think Xen is involved somehow. So do the e1000e
devs, as I posted this problem to their mailing list first, they
pointed to xen developers.

I found this issue back then too. The pcie_aspm=off parameter is
there, even now, it didn't change anything.

[    0.000000] Kernel command line: placeholder root=/dev/md1 ro
consoleblank=0 pcie_aspm=off
[    0.000000] PCIe ASPM is disabled

The EEPROM fix they mention is for 82573V, 82573E, 82573L only. My NIC
is 82578DM. Tried anyway.

# bash fixeep-82573-dspd.sh enp0s25
No appropriate hardware found for this fixup

The script searches for 8086:108b, 8086:108c or 8086:109a. My NIC is 8086:10ef.
