Divide by zero. Looks like ACPI is now passing bad values into the

Does this make the oops go away?
Other values will still cause divide-by-zero (any divisor in 0..9 will do
it). Besides, we're dividing with _old_, not new, so that's the one we
should likely check.

Indeed... I get two of the debug printks from the patch, but in the
end I still oops due to a div-by-zero with EIP in time_cpufreq_notifier.
I'll try and look into Linus' suggestion about printing out stuff from
adjust_jiffies() in cpufreq.c and will report later.
Thanks,
