Got this during boot on an IBM x345, three hour old kernel.
Last working kernel is from 5 days ago, later than that hangs
after probing the mpt controller (don't have the details on
that now since this happened while I was about the debug the
mpt issue).

Timecounter "ACPI-safe" frequency 3579545 Hz quality 1000
