Hi All,
I've got a OpenBSD installation on Microsoft Hyper-V, and there is a
strange issue related to time.
Actually the clock seems to be running fine, but all of the sleep
operations expire 2 times too fast.
I.e.:
# date; sleep 60; date
Mon Dec 1 18:23:18 CET 2014
Mon Dec 1 18:23:48 CET 2014
Counting the time with mechanical timer shows "exactly" 30 seconds
instead of 60.
Also other tools, like ping are giving strange time related output,
twice a second.
Disabling ACPI does not help.
Changing kern.timecounter.hardware does not help.
The described behavior happens on 5.5, 5.6, i386 and amd64 and all of
the combinations.
Please help.
Further details:
kern.timecounter.tick=1
kern.timecounter.timestepwarnings=0
kern.timecounter.hardware=acpitimer0
kern.timecounter.choice=i8254(0) acpitimer0(1000) dummy(-1000000)
