Secure lot is disabled, but TPM is needed for Windows disk encryption. The BUG is also present in the latest vanilla kernel from kernel.org. Will test things out and report my finding.

Here is the screenshot where the boot process stops: https://photos.app.goo.gl/6b7D2SsGBpgKWLd1A I installed old kernel packages out of local deb cache (linux- image-5.3.0-19-generic), initramfs regenerated, same boot options and was able to boot fine. I assume something went wrong with new security patches, ucode for intel CPU seems not to be an issue, because old kernel booted with newly generated initrd image.
