I'm still having the issue on kernel 3.1.10-9.27, no matter what I
attempt or try, ubuntu always thinks the nexus 7 is about dead.
I was curious if there was anymore on this as there hasn't been a post
in a month and searching for this issue returned nothing other than this
site.
I'm not sure
I can confirm the same issue with Ubuntu 18.04 (used the DVD). SSSD
cannot resolve the the backend and then says it's offline. Restarting
SSSD after a reboot always resolves the issue.
I've found two workarounds in 18.04:
1) Use your own resolv.conf and not rely on systemd-resolved.service.
