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 Upgrading microcode, i.e. adding initrd=\boot\intel-ucode.img to kernel, resolves and kernel boots. Resolved as this is not a kernel bug. |
