I am running on an old machine without PCID (I just checked) and I cannot boot anything later than the end of series 4.13. The panic occurs in the acpi driver and can be prevented by switching acpi off, but obviously that's not a preferred solution. Unfortunately, because it happens so early in the boot sequence, I haven't been able to capture the full traceback even with pause_on_oops set. I originally thought that this might be linked to some acpi errors reported by earlier kernels. By dint of much editing of dsdt and ssdt files, I have managed to clear all of these, but the panic continues. Unless I can find some solution, I shall have to build my next LFS with an older kernel than the native one. I read somewhere that there may be an incompatibility between newer kernels and gcc-7.
