@mitu I confirmed that the initial freeze reported in November is not the same as the freeze I am experiencing. I also confirmed that this commit in ES-dev from 26-Feb is causing my RPi4B freeze. Only trying to understand why, since I'm certain that when I first received this commit, everything was fine with my system, and had been for quite sometime. I only started noticing random freezes after updating RPi software with sudo apt update and sudo apt full-upgrade on June 12th, 2021.
HYPOTHESIS #1: Something in the commit may be incompatible with the latest vlc-bin: 3.0.12-0+deb10u1+rpt2.
I ruled out overclocking, as I receive the freeze as often overclocking as not overclocking.
Kernel and firmware also may be ruled out. I rolled back to January, well before I noticed issues and freeze still occurs. Possible user-error on my part, but I doubt it.
I also compiled a version of vlc (version 11) but I failed to get it to render with the screensaver (or video snaps)... I may try again to prove or disprove my hypothesis above.
Beyond that, I'm out of ideas. Something changed since that commit. Not sure how many people are running ES-dev. The improvements are remarkable. But to remain stable, I'll have to stick with stable.
Hope this information is helpful.
