The most suspicious thing is:

IOW, a (dead) kernel, which does not contain the new TSC ADJUST verification
mechanism.

If you send patches against mainline in future, then please always verify
that the problem persists with the mainline kernel.

Can you please boot something more recent - at least 4.19 LTS - on that
machine and let it run for a couple of days to check whether there are 'TSC
ADJUST' related entries in dmesg?

Thanks,
