Impending rant, because I think it is indeed a hardware failure that was caused from the kernel upgrade. I successfully downgraded linux-compiler-gcc-10-x86 and linux-kbuild-5.10 to their 5.10.28 versions from testing. As usual, it failed to boot properly after shutdown. I then decided to completely remove nvidia legacy 340 and give nouveau a chance, although I hate it and the room temperature was high already, so the risk of frying the card was also high. Nothing changed, blank screen from boot to poweroff (via ssh). Out of curiosity, I ran lsmod on both nouveau and nvidia (while it was already installed). And none of them showed up in lsmod! Moreover, lightdm was not running at all and I cound not even switch to a tty (not that I could when the problem first started). Then I got mad and went for a walk to calm down. I came back a few hours later and I also borrowed an ati 6450 from a friend to try. I pressed the power button and the system booted up as usual, using nouveau for the very first time (maybe second) ever. I ran poweroff, it shut down, I pressed the power button again and the same thing happened. Blank screen, nothing on lsmod etc. Then I replaced it with my friend's ati so as to be able to come back and write all this text here. I have no way to test the gpu (e.g. no spare pc), however, if it is a hw failure, it will be the second time debian destroys one for me. First time was on summer of 2011, when debian decided to remove fglrx from the repo and force me to use radeon for my 3850 after the upgrade to a new kernel. Back then, radeon was so limited in capabilities that it could not do powersaving. Long story short, my 3850 gave up the ghost ~1 month later, after running in max clock speed for a month. Sadly for me, history has probably repeated itself today, and I don't know why. What was changed in that damn update that f-ed up my gpu so badly? This gives me one more reason to leave debian after 13,5 years and move to arch. I had taken the decision to go there if nouveau becomes my only way to make my old gpu work in debian, now I have one more.
