I started seeing the issues that Sergio mentioned lately as well. I think this was caused by the recent automatic move from 5.8 to 5.11. I had the oem kernel installed (20.04 install) but then apt recently moved me to the hwe-5.8 kernel. More recently apt pulled in hwe-5.11 and I believe that is when I started seeing this issue.
I didn't look at this super carefully, but it appears that some packaging for the lenovo oem-sutton.newell-ace-meta ppa transitioned me to linux-image-generic-hwe-20.04 (fine) which at the time was 5.8 (on Jul 22 linux-generic-hwe-20.04:amd64 5.8.0.63.71~20.04.45 got installed, according to /var/log/dpkg.log.1). I rebooted into this kernel and was happy. Sometime in July, 5.11.0.22.23~20.04.6 came into -security and -updates, but I didn't install it. Later I performed an apt-get dist-upgrade and was upgraded to 5.11.0.25.27~20.04.10 on Aug 6. Today I upgraded again to 5.11.0-27.29~20.04.1. As it happens, I did not boot into either of the 5.11 kernels and am still on 5.8 (5.8.0-63.71~20.04.1-generic). I reinstalled linux-firmware just now and it readily demonstrates the issue: $ sudo dpkg -i ./linux-firmware_1.187.16_all.deb (Reading database ... 260812 files and directories currently installed.)

As I have the i915 chipset on this device, I haven't rebooted yet as I need a functional system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889137 Title: HWE kernel is missing firmwares To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1889137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
