New Revision: 278230
URL: https://svnweb.freebsd.org/changeset/base/278230
Log:
Initialize ticks so that it wraps 10 minutes after boot to increase the
chances of finding problems related to wraparound sooner.
This comes from P4 change 167856 on 2009/08/26 around when we had problems
with the TCP stack with ticks after 24 days of uptime.
