John et al, # Forget SMP and go back to UP for now. Turn off ntpd if you are using it, then # do something like this: # # # ntpdate ntp.xxxx ; sleep 10 ; ntpdate ntp.xxxx # # And try it both with the timecounter set to TSC and with the timecounter set # to i8254. Here we go, kernel with your second patch, boot with kern.smp.disabled=1.
