>Release:        FreeBSD 2.1.0-Development i386
>Environment:

Any machine with a relatively recent kernel and the bpf compiled into the 
kernel on an active network.

>Description:

tcpdump seems to cause random reboots on active IP networks. At least 3
different machines on WC's ethernets have suffered from this bug in the
last week. Using a filter seems to cause the bug to occur more rapidly.
(Judging from what David Greenman said last week in a different context
 the bpf when used by tcpdump is causing a kernel stack overflow).

>How-To-Repeat:

tcpdump

Unknown.
