And what the FAQ doesn't cover is here: http://wiki.freebsd.org/JeremyChadwick/Commonly_reported_issues * 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). * Reference: http://lists.freebsd.org/pipermail/freebsd-questions/2006-October/133253.html -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
