Hi, jkbuha! Could you please upload your latest EFI folder for Mojave and write BIOS patches that differ from high sierra? Because this annoying KP's on start and back from sleep make me sickAfter some stress testing think I finally figured out the issue with random Mojave KPs on boot. Problem is that it's not good news.
Turns out Mojave's handling of the kernel cache on boot is more checksum-intensive than Sierra or High Sierra. So aggressive undervolting and/or overclocking will cause floating point errors whilst the kexts are being read from cache. Reducing the undervolt to -70mV worked (on the i7-7500U) and I haven't had a crash since.
Interesting because even on the more aggressive settings (-85mV), once the kext cache loads correctly the macOS kernel is more tolerant on higher undervolting. Windows bombs out at -75mV and Kali starts twitching at -80mV.
