RE: Supermicro H8DAE-2 support

Hi, Julian:

Thanks for the useful info; I think I will start with Vanilla 4.5 on the =
board first to see if it's even possible. If no luck, I will try 4.11.=20

Regarding the changes, I am actually new to the company and I do not =
know all the history and details, all I am told is "massive".

I think mostly are on the TCP stack. I will learn more about it in the =
next few weeks.

Again appreciate your fast responses and ideas/suggestions.

Thomas

It's a pitty you have kernel changes because if you had just userland =
requirements,
I'd run a 6.2 system and make a 4.5 jail to match the apps.

Since you have kernel changes that won't work. however I'd still suggest =

moving up to at least 4.11.
The changes between 4.5 and 4.11 were not that great, but a lot of newer =
hardware
was supported. Your kernel changes will nearly all apply with minimal =
change=20
(if any at all), but you may have a chance to get some newer hardware =
working easier.
There are also security and bug fixes.. in fact I'd go for a RELENG_4
system (i.e. from the 4 branch but after 4.11..  you compile it =
yourself).

what KIND of changes? (some changes can be ported forward to 5.x really =
easy too.
It depends on what kind they are and where they are.
