Ok, I included these options

to kernel config. Result was same, softdeps crashing system with and
without these options. And BTW I got that GoBSD recognise those 16 Megs on
motherboard. Just had forgot specify MANYSEG option on commandline.

Here is the output of first crash without those NKMEMPAGES options
enabled, [my comments like this]:

Result NKMEMPAGES options enable kernel was same except 

call_sicallback: 12417 more [... rest is missing from my paper, maybe I
was so sleepy...]

So what is this call_sicallback? I will provide what information you need
as long as you tell how to get it.
