Public bug reported:
This happened on 3 different laptops at approximately the same time. All
laptops were connected to the same accesspoint SSID (WeWork). All
laptops are Lenovo L15 Gen1 AMD laptops. All run Ubuntu 20.04.4.
Packages are:
linux-image-5.14.0-1036-oem 5.14.0-1036.40
linux-image-5.11.0-46-generic 5.11.0-46.51~20.04.1
After 30 minutes where multiple reboots were tried, the problem went away.
2 laptops are on 5.14.0-1036-oem, 1 is on 5.11.0-46-generic, all packaged as
provided by Ubuntu.
VirtualBox and AMDGPU are installed on all laptops concerned, but some
of the crashes happened before they were loaded in the kernel.
All reports were acquired from systemd-pstore, no other place had any
information about the crash.
