Source: linux Followup-For: Bug #989010 X-Debbugs-Cc: pitsior...@gmail.com First of all, I removed 5.10.38 because I want grub to directly boot to the working kernel without me having to select it via grub's advanced menu.
Yes, nvidia (340 legacy) is the reason the tainted message pops up. To be honest, I don't really want to remove nvidia (because unloading is not a real option), and let me explain why. First, I have to remove and purge every single nvidia package, so as to be sure nouveau isn't blacklisted somewhere and can be loaded. Second, I have to remove nomodeset from my kernel's boot parameters, because nouveau needs modesetting to work. Third, because nouveau does not do proper powersaving for almost any gpu, I will have to reinstall 5.10.38 and do all the testing while my gpu will be running at max clock speeds, and all that in a room that has 30oC now. That is the core reason I avoid and dislike nouveau. For the forementioned reasons, I would like to stick to nvidia and continue troubleshooting in a different way, e.g. why did the system went to sleep since I had disabled it completely years ago? Or why it has affected my system so much that even the post and grub were not shown? I must mention that I have already checked the package changelog for 5.10.38 and it does not mention nvidia somewhere. In other observations, my drive's precious space has gone down ~300MB after that incident and I can't find out why. I do not have a swap file or partition, apt's cache is in /tmp and /tmp is in ram (tmpfs).
