On my = Supermicro X11SSH-LN4F motherboard with E3-1260L v5 it takes over ten = minutes to get to kernel boot. After that performance seems normal = (though I=E2=80=99m still testing). This issue occurs when booting the = installer from a USB stick or when booting the installed OS over SATA.=20= I understand using UEFI resolves this issue, although I only have one = Skylake motherboard model on which to confirm this. I know this issue is = unlikely to be fixed for 10.3 release, but I think it should be noted in = the release and/or hardware notes. Skylake systems are going to be = increasing numerous this year, especially now Skylake Xeons are starting = to ship in volume.=20 I am happy to test patches and/or current on this server if that helps. = If you want more details on the motherboard/system I have started a post = on it at http://buildwithbsd.org/hw/skylake_xeon_server.html TIA Will=
