90ms is a relatively bad static frequency error; a good machine will be
around 10ms. That won't help a clean cold start.
I didn't check, but did you have the default min and maxpoll values. A
high minpoll might make it difficult to get the loop to converge from
there without overflows.

The kernel time discipline is turned off if you disable steps completely
(i.e. you set the minimum error for a step to be more than half a
second or you set it to zero).
