Sorry for a long time to answer and no logs. We've been testing the problem on irc channel. It turns out that the new kernel assigns new names to the network interfaces i.e. the original name (in kernel 62) was enP3168p5s3 and the new kernel assigned the same card and the same interface a new name - enP64624p5s3, therefore - no network obviously, as the /network/interfaces file contained old names. After submitting new names to the config file, the network is up and stable.
