It happened again. I have:
$ sysctl kern.version
kern.version=OpenBSD 6.0-current (GENERIC.MP) #2325: Fri Aug 5 23:28:36 MDT
2016
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Command I issued before kernel panic still the same (by openbox menu):
$ sudo halt -p
Tail of dmesg under kernel debugger:
$ dmesg

after $ c it added line:

The same, what was printed above, was an output of $ machine ddbcpu 1
