I have a potentially related issue. I upgraded to Catalina:
I upgraded my Late 2015 27" iMac to Catalina when it was released this month. Now, about once a week I wake up to a message "Your Computer Has Detected A Potential Problem", and there is a file open called "EFICHECK.DUMP".
The other day, I decided to clean out my hard drive, and install Catalina fresh from the recovery mode, and this morning once again woke up to this error.
I went to System Report and it shows that I have Boot Rom Version (Firmware) "170.0.0.0.0" but according to this site it should be 173.0.0.0.0

Could this be the issue? How does one fix this? I already did 2 installs (one from scratch) of Catalina. Computer runs fine, no crashes or errors, ever, until this after the Catalina upgrade.
