And yeah, your TSC frequency is astoundingly high. Way higher than
anything I have ever seen.
My guess is that we are miscalibrating the TSC frequency at least
once. The only major thing that changed in the frequency calibration
code between 7.1 and 7.2 is the introduction of additional delay(9)
implementations.
Let's see if removing them from the picture changes the result we get.
Can you compile and boot a -current kernel with the attached patch and
send the resulting dmesg?
Yes I could, but it will take me some time, I never ever compiled a
kernel :D
