Just noticed (NetBSD-8.99.26/amd64): ntpd[1575]: kernel reports TIME_ERROR: 0x4041: Clock Unsynchronized
This is after a ntpdate which succeeded in catching up the 3/4 hour that clock was behind by. I haven't seen this error before... Is ACPI-Fast a good choice? (I didn't choose...) # sysctl kern.timecounter kern.timecounter.choice = TSC(q=-100, f=2666902400 Hz) clockinterrupt(q=0, f=100 Hz) ichlpcib0(q=1000, f=3579545 Hz) ACPI-Fast(q=1000, f=3579545 Hz) lapic(q=-100, f=266767233 Hz) i8254(q=100, f=1193182 Hz) dummy(q=-1000000, f=1000000 Hz) kern.timecounter.hardware = ACPI-Fast kern.timecounter.timestepwarnings = 0 Cheers, Patrick
