x86 CPU CATERR detected

I've updated to the latest macOS Catalina 10.15.4 (including April supplemental update) and started getting a lot of kernel panics, like several times per day.

The only condition I noted when it is does happen - it is a screensaver. The MacBook works fine until I go away and then came back, seeing the MacBook powered off or it will power off when I'll press the key or trackpad.

It is really annoying! The device for 4K+ euros and its resiliency sooo bad that I want to migrate back to Linux sometimes. Even Windows under Bootcamp is more stable than MacOS (no crashes at all).

One of the panics I'm getting is:

panic(cpu 1 caller 0xfffffff01ac537b4): x86 CPU CATERR detected

Debugger message: panic

Memory ID: 0x6

OS version: 17P4281

macOS version: 19E287

Kernel version: Darwin Kernel Version 19.4.0: Mon Mar 2 20:38:56 PST 2020; root:xnu-6153.101.6~2/RELEASE_ARM64_T8010

Another one that happens pretty regular:

panic(cpu 8 caller 0xffffff800a816487): "AppleIntelFramebuffer::setPowerState(0xffffff8352a1a000 : 0xffffff7f8dda8d88, 1 -> 0) timed out after 46021 ms"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6153.101.6/iokit/Kernel/IOServicePM.cpp:5296

WTF, Apple?
