Subject: Re: intel i225 NIC loses PCIe link, network becomes unusable)

Hi all,

I couldn't see any replies to this issue (but I'm also not subscribed to 
the list, probably something I should consider...) but I have another 
instance of the issue reported.

Now cc'ing other parties in the hope to get indication this is already 
solved (somehow) or will be looked into.

Additional kernel messages about latest case below the quoted original mail!
