For a few days, my Catalina installation was behaving well. Now, I get not-infrequent kernel panics. I have run Etre-Check, which did not flag any problems. I have also removed Ejector form my startup items (the panics started a few days after I installed it), reset SMC, started in Safe Mode (and restarted), checked memory with TechToolPro, reset NVRAM, and run SMART. There has not been enough time to see if the problem recurs, but the report has been sent to Apple, but maybe someone here can diagnose this for me:
