Yep, false alarm, sorry. The bug is not fixed yet. It's interesting that after the clean reboot (NOT a hibernate/resume cycle) the network adapter can work for indefinitely long time as long as it is used constantly (I've ran a flood ping on another machine in my home network while browsing the Web, and it worked for 3 hours non stop). It can be related to some kind of power saving / device suspension state.
As far as I know, problems start once a message like this appears in dmesg: atl1c 0000:07:00.0: irq 46 for MSI/MSI-X -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1175091 Title: Cable Ethernet conn.
