Nothing fancy, and nothing changed, complete dmesg is below. The ep0 and the
ISDN stuff were not used when the overruns happened, no network traffic
besides the NFS stuff, so ipfilter wasn't active either (it's used over the
ISDN interfaces only). The lpt0 is attached to a parallel DCF77 receiver and
polled once a minute by xntpd, this hasen't changed, and the overruns are
not in minute intervals (there are bursts of a few overruns in irregular
intervals).
