Comment 18 for bug 1897185

Another system failed under 20.04.1: A T480 that hadn't been used for a while, set up dual boot Ubuntu 20.04 and Win 10. Ubuntu had updates waiting including the 20.04.1 updates from several weeks ago. As soon as that installed and the system was restarted, malfunctions began. The system was docked (UltraDock) running lid closed with an external HDMI display as primary and a Lenovo USB external keyboard. The dock also had a Logitech USB dongle for the wireless Logitech mouse.

Immediately upon restarting, the system suspended as soon as the login password was entered. In looking at the logs, it appears that the action immediately preceeding the suspend was loading the Logitech module. This now happens every startup unless the Logitech mouse is turned OFF during startup.

The splash screen is turned off to prevent the spinning logo hang (done on the first restart after the updates -- after resuming from suspend -- to prevent the hang); the initramfs error messages are on full display with every start.

This system includes discrete nVidia graphics on an 8th gen Intel chipset with Sierra Wireless. Ubuntu is using the proprietary nVidia drivers, which were loaded prior to the 20.04.1 updates; those updates did install the most recent nVidia driver. This system does NOT have Dropbox loaded.

Posting this to provide another data point that I hope will help to pin down this problem. FYI, this is now 3 of 3 Ubuntu LTS 20.04 systems here that have been afflicted with the Ubuntu 20.04.1 bugs.
