CSA gigabit ethernet

I have been trying to convince Supermicro support that the CSAB entry 
would need _PRT Method to work properly and have not really got a "go 
away" message but not "we´ll fix it" either.

Obviously this causes problems with the CSA gigabit if device apic is 
enabled and the APIC is enabled in the bios also. (watchdog timeouts, I 
also saw a PR open on the symptom)

Comments? I put the whole dump to http://helenius.fi/p4sctii.asl

The board in question is P4SCT+II. I suspect the problem exists in all 
Supermicro boards with CSA.

Running on 5.2.1-RELEASE or 5.2-CURRENT behave similarly.

Disabling APIC in the BIOS makes the system usable.
