Random and Unexpected System freezes, Opencore 0.7.3 Big Sur 11.5.2

[zakaghbal]

I thought my system was stable but I just got a random system freeze, had to do hard reboot. What could possibly be the cause? USB mapping done. Kexts updated. Opencore 0.7.3. everything seems to be in place. This really driving me mad. Because they are unexpected and random. Hackintool doesn't show any Logs after the reboot. Appreciate the help.

I'm on Mac OS Big Sur 11.3 [ same issue with 11.5.2 ]. It can be stable for hours then a random freeze.
