Big error

Hi all

After I have installed the program where I get up this message.

Are you running in a VM? There are other threads about this happening in various environments with different ways of setting clocks/NTP etc. e.g. a recent thread: http://forum.pfsense.org/index.php/topic,57234.0.html

I would hope he wouldn't be sending a photo of a screen if it was a VM, but you never know! ;)

Another possibility is a bad kern.timecounter.hardware selection.
Usually the default choice is TSC. E.g.

[2.0.2-RELEASE][root@pfsense.fire.box]/root(2): sysctl kern.timecounter.hardware
kern.timecounter.hardware: TSC

However if your processor has a variable frequency for whatever reason, speedstep, thermal throttling, turbo mode etc, then TSC can vary causing problems.

You can check what your options are:

[2.0.2-RELEASE][root@pfsense.fire.box]/root(6): sysctl kern.timecounter.choice
kern.timecounter.choice: TSC(800) i8254(0) dummy(-1000000)

The number is the quality of the time counter, TSC is highest quality as it ticks the fastest. You can choose, say, i8254 instead:

[2.0.2-RELEASE][root@pfsense.fire.box]/root(7): sysctl kern.timecounter.hardware=i8254
kern.timecounter.hardware: TSC -> i8254
[2.0.2-RELEASE][root@pfsense.fire.box]/root(8): sysctl kern.timecounter.hardware
kern.timecounter.hardware: i8254

If that solves the problem you can add the sysctl to the table in System: Advanced: System Tunables:

On physical hardware, that's usually caused by a buggy BIOS and upgrading it generally fixes. Though mucking with the timecounter sysctls may be a work around, as Steve noted.
