Hi Marcelo,
I tried to validate the test kernel provided by you in comment 23. I am not able to load the kernel. When I select the kernel from the grub menu, the loading gets stuck at "Loading initial ramdisk". I tried it with secure boot disabled too, just to be sure we are not making any mistakes with the signing part. I am not sure if I am missing something here. Can you please help resolve this?

This means that PCR values calculated from the event log will not match the actual PCR values on the machine for PCR indices into which these events are measured. There are upstream patches to fix this in the mainline kernel tree: https://lore.kernel.org/lkml/20190520205501.177637-1-matthewgarr...@google.com/ --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found.
