I'm about to build a server with a supermicro X11SSL-F motherboard and a Xeon E3-1240L v5 processor. The SATA ports should be AHCI compliant, and it looks like the i210-AT ethernet is supported by the em driver, so I think everything should work ok. But it's pretty new stuff, so I wanted to check and see if anybody was aware of any problems or issues with OpenBSD 5.8 and the latest Intel processors and chipsets before I pulled the trigger on it.
Thanks much!
