[SOLVED] Random reboots and crashes Ryzen and AMD GPU under Linux

After months of debugging, the random reboots of Ryzen 3700X/AMD GPU could be solved by changing the grub configuration to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.ppfeaturemask=0xffffbffd"

which seems to help quite a number of people if 'journalctl | grep -i "hardware err"' returns errors like bea0000000000108 and microcode 8701021 or 8701013. From this thread:
