* EIST (Intel SpeedStep) incompatibilities with Supermicro PDSMI+ motherboards (and possibly others) * Symptom: kernel outputs messages like kernel: calcru: negative runtime of -XXXXX usec for pid XX * Workaround: Disable the EIST feature in the BIOS. You can still achieve ACPI-based processor
     frequency throttling by using powerd(8).

What I find interesting is I hadn't seen these until this kernel update :(

Same problem here with Tyan Toledo i3000R (S5191) motherboard if cpufreq module is loaded.

7.0-RELEASE (AMD64) didn't have this problem.
