I would add this as a comment, but it is too big. On Fedora 27 on a Lenovo Flex 5 (intel i-7 8 cores) the only mention of LNK is

[~] $ dmesg | grep LNK

I surmise that the package named is somehow failing to initialize the interrupt links to each CPU core.

Yup. More specifically, PCI interrupts. Somewhere in the DSDT (or an SSDT) is a reference to those LNK* objects that is incorrect. The dmesg output says the LNK* objects are being created, but the errors and exceptions are saying that the name being used to get to them in the DSDT doesn't exist -- something like using the name "LNKA" when a full path like "_SB.PCI0.LNKA" should have been used. And, IIRC, the LNK* objects are used on older PCI devices, which might provide some additional clues (vs MSI, for example).

As part of my work on the ACPI standards committee, I like collecting the bad tables folks have written, so I'd love to get a copy of all the files in /sys/firmware/acpi/tables, if you get a chance.

Comments

You mean the contents of those pseudo-files, right?

That is correct.

LNKE-1 are not mentioned among exceptions inbefore interrupt disables them.

Not enough points to attach, so I'll just paste the hexdump.

$ hexdump /sys/firmware/acpi/tables/*
