Public bug reported:

Description:    Ubuntu 20.04.2 LTS
Release:        20.04

Kernel: 5.4.0-72-generic

Problem Description:

When rebooting the system, a bus fatal error is generated by the system
hardware pointing to the BCM57XX network card. Upon reboot the error is
cleared.

Dell notes this in their release notes for Ubuntu 20.04 LTS -
https://www.dell.com/support/manuals/en-us/ubuntu-
server/ubuntu_20.04_rn_pub/A-bus-fatal-error-is-detected-on-BCM57XX-
card?guid=guid-5094de74-f8fc-49ee-b8c1-47a44e4855e3&lang=en-us

I manually installed the latest mainline kernel
(5.4.116-0504116.202105021035) and the error does not occur.
