We've same issue w/Supermicro boards if IPMI daughterboard installed. A 
problem looks as PHY reg reads/writes fails.
I suppose they use buggy (incompatible) technique to make "virtual lan" 
channel for remote KVM support.
On some systems we can start interfaces via warm boot, sometimes not, 
sometimes we can recover it w/powercord unplug, sometimes - not.

100% workaround: remove IPMI daughterboard.

Also, I've a several systems w/IPMI which works Ok.
