Hi Folks,
I am trying to run FreeBSD 7 on Microsoft Virtual Server 2005 R2, Windows Server 2003, on a Dell 2950.
I am having a problem with the system clock running excessively fast, I initially tried installing 7.1 release but received a nearly continuous stream of the "calcru: runtime went backward errors", I tried rolling back to 7.0, and it improved somewhat, but I still received regular "calcru" errors, and it the system clock was running to fast for ntpd to keep up with it, I set sysctl kern.timecounter.hardware to i8254 (it tries to default to ACPI-safe), which helped more, ntpd is now able to keep pace with it, but only barely, and I haven't seen any "calcru" errors yet.
From the boot time dmesg, on the CPU line, the frequency reported with in the parenthesizes varies on almost every reboot.
Are there any other adjustments I can make to get this under control?
Following are samples of sysctl values, dmesg, and a short log sample to show the time and time reset rates.
