>Description:
I started seeing those calcru messages when I upgraded from 9.0-RELEASE to 9.1-RELEASE amd64. I had never seen them with 9.0.

They appeared after suspend/resume to RAM cycles (acpiconf -s3).

I tried all the proposed solutions (http://forums.freebsd.org/showthread.php?t=2805) without success, then I reinstalled the system with i386 and I never saw them again.

Recently, I installed (for other reasons) the latest release of PC-BSD (9.1-RELEASE amd64) and these messages come back after going to sleep.

My old box is based on a MSI MS-7142 K8MM-V motherboard (VIA K8M800) with AMD Sempron Processor 3400+ (1999.83-MHz K8-class CPU, socket 754), maybe the limited 64 bit support is the problem?
>How-To-Repeat:
Install (or upgrade from 9.0) 9.1-RELEASE amd64 on this hardware and make a cycle of suspend/resume to RAM (acpiconf -s3).
>Fix:
Use the i386 release or downgrade to 9.0 (not tested).
