Comment 7 Benjamin Braun 2017-10-24 01:56:07 UTC 
Oops - there is some log output that might be key to the issue.

Adding "earlyprintk=efi" to the kernel boot parameters gives the following two lines:

Memory KASLR using RDRAND RDTSC
[    0.00000] [Firmware Bug]: TSC_DEADLINE disabled due to Errata: please update microcode to version: 0xb2 (or later)

so possibly a duplicate of another bug, will mark resolved when I find it
Comment 8 Benjamin Braun 2017-10-24 02:03:40 UTC 
Upgrading microcode, i.e. adding initrd=\boot\intel-ucode.img to kernel, resolves and kernel boots. Resolved as this is not a kernel bug.
