Public bug reported: After system reboot this morning, my wifi adapter was not found. 18.04.3 and -60 kernel. I followed advice by lotuspsychje in #ubuntu to test -58 and found that -58 works, but -60 does not. He also had me reboot using GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.fastboot=0 intel_idle.max_cstate=4" in /etc/default/grub and that did not fix the issue. After these steps, he requested I file a bug report for my system and attach the dmesg to the report
1. Ubuntu 18.04.3 LTS 2. N/A 3. Boot up and wifi adapter found. 4. No wifi adapter found after -60 update, still works on -58.
