Hello, list!
I've a problem with the clock of an old AMD K6-2 machine (dmesg below)
since the 4.2-release upgrade. The clock worked fine before with 4.1.
Because of this problem I upgraded to 4.2-current, but that didn't
help.
192.168.0.21 and 192.168.0.22 are local routers, ntpd can sync their
clock without problems, and other local machines sync fine using them.
I tried also with pool.ntp.org on the problematic machine, with same
results. I see this in the log after removing /var/db/ntpd.drift and
setting the clock correctly via BIOS menu while rebooting:

...and so on. Sometimes ntpd can't sync the clock even if the clock is
set correctly via BIOS menu and with /var/db/ntpd.drift removed before
rebooting, but if I'm lucky, it works for maybe a day. Unfortunately
there's no second time source and the BIOS has no ACPI:
$ sysctl kern.timecounter
kern.timecounter.tick=1
kern.timecounter.timestepwarnings=0
kern.timecounter.hardware=i8254
kern.timecounter.choice=i8254(0) dummy(-1000000)
In fact the clock of that machine isn't that bad, it might be off a
few seconds or even a minute per day without ntpd running, but not as
much as with ntpd running. Is this simply a problem with broken
hardware, or is it possible to fix this with the existing clock and
software somehow?
Thank you for your help!
Tas.
