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.

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. >=20 >> >> >> Thanks >> >> Thomas >> >> >> No virus found in this outgoing message.
