3 kernel dump can be found here - https://mail.proc.ru/temp/xz.zip
Comment 1 Hiren Panchasara freebsd_committer 2016-04-11 17:46:52 UTC
I am not sure what could cause this. I don't see much changes to that code except r272089 (from Sean - cc'd). But I don't think can be a cause of your crash. 

Unsure if any change in igb can cause this.

You are reporting that this worked fine on 9.3. Is it possible for you to further bisect this? Try 10.1 or 10.2 and see?
Comment 2 h-k 2016-04-11 17:51:52 UTC
Yes, i can try 10.1 or 10.2 but not too fast, probably on this weekends (16-17 apr).
Comment 3 Sean Bruno freebsd_committer 2016-04-11 18:18:23 UTC
(In reply to h-k from comment #0)
The crash dumps at the url referred to don't seem to exist.  :-(
Comment 4 h-k 2016-04-12 05:38:39 UTC
(In reply to Sean Bruno from comment #3)

my fault. was wiped by crontab.
