One of our systems is consistently failing to refresh to this kernel snap. We can't see any kind of kernel messages from it since there's no serial console or anything, but remotely I'm seeing that it never comes back after the refresh happens. If I reboot it once or twice, I can eventually get it to revert to the previous kernel and boot. I asked someone in the lab to take a look, and it was at the normal ubuntu core console screen after refreshing the kernel, but it appeared that it was still waiting for an IP address. Did something change in this version that could have impacted networking?
The system details are:
Dawon-i NUC (NUC7i5DNHE)
Intel(R) Core(TM) i5-7300U CPU @ 2.60GHz
Ethernet: Intel Corp. - 8086:156f

There is a new bionic/linux kernel in -proposed, kernel 4.15.0-180.189 was already promoted to -updates. I'll duplicate this tracking bug against the snap tracker for version 4.15.0-182.191 so we can get a new pc-kernel built and tested.
