How horrible is horrible?
I run a 386 SMP kernel from the same period, and I see a mean
hourly offset of |0.008| sec. For an aging peecee in an imperfect
environment, this doesn't strike me as horribly bad time disciplining.
Do you see a difference between an SMP kernel's behaviour and
that of a single-processor kernel on that machine?
ps - this would be a neat excuse to resurrect the branch, though. -:)
