[Bug 1938983] Re: missing modules after 5.11.0-25-generic update

[Luca Ferroni]

Bug affects also to me in upgrading to 5.11.0-27

~$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 20.04.3 LTS
Release:	20.04
Codename:	focal

The solution proposed by @MikeR works for me:

I have created a file t.txt with missing modules with the base
LinuxFromScratch URL: https://anduin.linuxfromscratch.org/sources/linux-
firmware/i915/

and then

~$ cd /lib/firmware/i915/
/lib/firmware/i915$ cat ~/tmp/t.txt | while read a; do sudo wget $a; done
/lib/firmware/i915$ sudo update-initramfs -u -k all
update-initramfs: Generating /boot/initrd.img-5.11.0-27-generic
update-initramfs: Generating /boot/initrd.img-5.11.0-25-generic
update-initramfs: Generating /boot/initrd.img-5.8.0-63-generic

Thank you all guys, maybe files should be integrated in `linux-firmware`
package? Can any janitor confirm pls so me or someone of my FSUG can try
to propose a patch for the package itself?
