Just a heads up on the original issue, which is FreeBSD's timer/clock stopping under ESXi 5.0 and some later versions of VMware Workstation. I've gotten a few direct messages that this thread ranks high on Google but people are missing the solution. A few months ago I found this forum posting (I believe this was linked in this thread already) http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2012-03/msg00201.html The long and short of it is that changing the kern.timecounter sysctl value to ACPI-fast or (ACPI-safe if you're not running 9.x yet) fixes the hanging issue so far for us. To temporarily enable it under 9.x: sysctl kern.timecounter.hardware=ACPI-fast Pre 9.x (which doesn't have the ACPI-fast mode): sysctl kern.timecounter.hardware=ACPI-safe To make this persist across reboots and be enabled by default add this line to your /etc/sysctl.conf Under 9.x: kern.timecounter.hardware=ACPI-fast Pre 9.x: kern.timecounter.hardware=ACPI-safe Hope this helps anyone running across this issue. -- Adam Strohl http://www.ateamsystems.com/
