OK, so the e1000 (eth0) IRQ is now shared with your ATA controller - not
good.

Unless your e1000 is on a real PCI card that could be flips around in
some slots and/or its IRQ can configured in the BIOS, I'm afraid there
is no way around MSI. But if MSI should not used by the e1000 even if
enabled, then your system is actually unusable for RT-Ethernet. So, try
to re-enable MSI and check if the IRQ assignment changes. eth0 must
finally end up with an exclusively used IRQ.
