--- Comment #11 from Dennis Schridde devurandom@gmx.net --- One more thing: It appears as if the first "cold" boot usually fails -- the kernel hanging after "[drm:amdgpu_get_bios [amdgpu]] *ERROR* ACPI VFCT table present but broken (too short #2)" and the blinking cursor freezing. "Cold" boot meaning booting the system after it was powered off. The next boot (hard resetting the machine) usually succeeds. I write "usually", because sometimes the first boot already succeeds, and sometimes it needs two hard resets to bring up the machine successfully, but I cannot yet make out a pattern. I will enable verbose and debug command line arguments to hopefully get some more information, the next time it happens.
