Re: Intel X540-AT2 and Debian: intermittent connection

Re: Intel X540-AT2 and Debian: intermittent connection

and it didn't make a difference. I suspect that Debian might be doing something differently or not doing that Fedora does which causes the intermittent connections. Any ideas?  Backups over an 1GB link are excruciatingly slow ... Update: I booted a Fedora live system and the connection is also in
