Sure, no problem. Just done that and run with debug turned on. It seems to help - I'm no longer getting the wired networking turned off. Feel free to close this bug if you like. I *do* get a glitch in the networking, though, which looks like it's coming from line 124 - it's trying to adjust (un-throttle) the network. That's giving a suspicious error in line 208 of the log: Dec 7 17:35:40 tack laptop_mode[14441]: + [ x0 = x1 ] Dec 7 17:35:40 tack laptop_mode[14441]: + /sbin/ethtool -s eth0 speed 1000 Dec 7 17:35:40 tack systemd[1]: Stopped Run anacron jobs.
