I just realised you are using OpenCore. Is there a fix for Clover?
Unfortunately I don't know of any Clover fixes but if there is any you'd have to look in "Kernel Patches" section and do some trial and error with different flags on and off "NON-PERMENANTLY" by turning on and off the flags in Clover bootloader screen by going to to Options page before booting to macOS, this way the flags that you change are only effective for that boot session and not saved into your config.plist so if you get a kernel panic you can just reboot and you're back to bootable config and after finding out which flag is the fix for your issue you can edit your config.plist for permanent change. ;)

Thanks for this patch. I have been having persistent shutdowns (out of nowhere) on Catalina despite the same machine being absolutely robust under Mojave, High Sierra and Sierra. Notably the machine does have a DVD r/w drive. Am trying this patch to see if it does the trick. Will revert back with news. Thank you.

Just to circle back. This completely solved my issue. There are no more random 'power downs' and reboots. For clarity my machine has a DVD r/w drive and Trizel I added your patch to the KernalToPatch -- works like a charm: thanks!

Thanks. I'll try this today. Question though if power state is being timed out does it mean the system is unable to sleep?

Hi, the problem was an outdated Bluetooth firmware. It was very old and causes kernel panics. After patching the firmware using the following the problem was solved. Thanks a lot.
