Subject: Re: kern/36204 (makphy failed to work on Intel S3000AHLX server board)
Date: Wed, 12 Jun 2013 08:59:36 +0200
Hi,
yes, we have some ot them but currently all off them are used in
productive environment - with this interface unused ....
I'm currently preparing an upgrade to 6.1 for all systems and I will
have a look at this as soon as I get to a system with this board.
At least in 4.x the problem was still there.
best regards
