This actually reeks of a bunch of microcode and firmware issues that got fixed in the last months. Ensure you have microcode 0x73 or later, that's actually a good hint both the microcode and the PCH firmware are not crash-prone buggy crap.
As far as I am concerned, the kernel should refuse to boot on any Skylake box with a BIOS older than 2016 or running a microcode revision earlier than 0x73. That would certainly be a lot more truthful to everyone involved.
If an UEFI update is not available yet from your vendor, ask for your money back. A properly up-to-date UEFI for Skylake with SGX support will have microcode 0x83 or higher. If it has SGX support permanently disabled by UEFI, 0x76 is enough.
