I have precisely the same problem (which is not surprising since I also
have precisely the same motherboard).  Unfortunately I also have an ATA
CD-writer and four ATA disk drives (two of them SATA).  If I boot with
ACPI disabled, the ethernet interface (em0) works but the SATA driver
breaks ("missing" interrupts).  This situation is most frustating since
both drivers seem to work ok in both release 4.9 and 5.1.

Let me know if you discover how to fix the ethernet problem without
disabling ACPI.  I would really like to be able to run release 5.2.
