Yes, all debug options are stay by default.

I have updated ipfilter to 4.1.27 until cvsup with tag=RELING_7 and sources
was from 10.10.2007 which system shows me panic with _sx_sleep() and
_rw_sleep() with ipf 4.1.23. After some tests :)) /ping, smbfs,
telnet, etc.../ Update of ipfilter was finished at 17:00 GMT+3, now:
# uptime
23:51 up 7:12, 2 users, load averages: 1,32 1,23 1,09

Now I'm have update CVS-tree, and build world for RELENG_7. With
ipfilter 4.1.23 system stay alive 1-2 min with inet work, I have been
compelled to disable ipfilter (ipf -D) for work with network.
While any failures are not present, all works normally.
