>Description:
The kernel global variable "tickadj" is set to a default value of
240000 / (60 * HZ); /* can adjust 240ms in 60s */
which is 40 us adjustment per tick.
NTP works much better with a tickadj of 5 us adjustment per
tick.
>How-To-Repeat:
see xntp documentation; we shouldn't need to run tickadj to
patch it on each boot..
>Fix:
change /sys/conf/param.c::tickadj to be set equal to the
constant "5".
