I tested it with kern.timecounter=i8254 and with kern.timecounter=TSC, but both are to fast to. It's not extreme like with acpi, but both to fast to. Both are 1 or 2 Seconds to fast per Minute: ntpdate ntp 9 May 10:26:57 ntpdate[776]: step time server 192.168.0.20 offset -0.690100 sec ntpdate ntp 9 May 10:36:08 ntpdate[801]: step time server 192.168.0.20 offset -9.297237 sec sysctl kern.timecounter.hardware kern.timecounter.hardware: i8254 -- René Maroufi info@maroufi.net
