No, using the default fedora kernel I cannot get into S0ix. Also, mirroring from gitter: After updating my BIOS and reinstalling Linux, I had some issues to get into s0ix...

It doesn't work with 5.3-rc5 either, sadly. Using the stock kernels it doesn't even get into the higher packages (C7-10 just show 0). Building a kernel with *just* `surface_acpi` could...

Actually, when you look further into the LPIT table, you can find the same `FunctionalFixedHW` entry a second time. For SB1, it is simply duplicated, while for SB2 it is...
