Comment 4 for bug 1947188

I cannot reproduce this. Your system must be misconfigured somehow or otherwise in a bad state. I fail to see how this could be a linux-firmware package problem.

ubuntu@ubuntu-focal:~$ sudo dpkg -i linux-firmware_1.187.19_all.deb
(Reading database ... 78866 files and directories currently installed.)

One indication that the system is not happy is that the kernel is flooding the logs with:
