@Debian_SuperUser Inspired by your comments in #13, despite the derision, and inspired by @GFdeb12, it sent me to various websites ending here: https://cdrdv2.intel.com/v1/dl/getContent/671098 It's hard to see how altering the msr registers would help if they depend on the loading of the msr...

Actually it was cpu load documentation in the kernel docs that I consulted. Unfortunately the kernel doesn't provide stats for cpu activity in the earliest stages of booting. Hence there are difficulties in determining the extent of its work, but as mentioned, the design is to work closer to...

The garbage collection process occurs automatically, usually during a system idle. Trim, on the other hand needs to provide the ssd with the information about its deleting of files and that those file pages need to be made available for new information. So it's partially a timing matter, the...

If the machine doesn't have the package: firmware-amd-graphics, installed, perhaps install that, reboot and see if it makes a difference.

In relation to openscap and lynis, both are available in debian: [tom@min ~]$ apt-cache show openscap-<TAB> openscap-common openscap-scanner openscap-doc openscap-utils [tom@min ~/notes]$ apt-cache show lynis<TAB> lynis

There are a number of AI sites that have been useful here: Gemini, ChatGPT, Copilot, Perplexity. They have provided info on configuration, code, errors and then a lot of more general queries. If one is not so helpful, often another is. Asking the same question to the one AI site often provides...

The passwords in the BIOS refer to passwords for the BIOS, that is, a password to enter the BIOS itself, and not for the operating system. For the linux operating system the root password can be created from the process described in the link in post #49 above in this thread. That works! There's...

Here's a standard means of resetting or creating a root password: https://linuxconfig.org/recover-reset-forgotten-linux-root-password

This page could be quite helpful: https://www.debian.org/doc/manuals/securing-debian-manual/automatic-harden.en.html The whole manual is very comprehensive for debian on the issues.
