The current (5.12.0 kernel) problem symptoms show some "improvement". I at least got to the point that the login screen displayed, but it had a bit of pixelation/distortion in a few areas indicative of "bad things about to happen". Then I got the expected system lock-up, just as I originally reported: had to hit the reset switch to recover. --Bob

I have lost track about this issue, so please fill me in as to whether the offending commit causing the regression has been bisected or not. Maciej
