Experiencing some seemingly random crashes since raspbian stretch, sometimes it occurs a few minutes after booting, sometimes it happens after running for a day, its not happening every day, so giving some proper reproduction steps is sadly a problem. Im using the raspi mostly as a firewalling device between 2 subnets. I've no clue about debugging kernel issues really, but both of the 2 crashes that i observed within the last coupe days since i attached a debug cable had this PC is at hash_net4_test+0x1f0/0x54c [ip_set_hash_net] line in common, so i suspect its something network related.

Hi. Did you ever get to the bottom of this? I am experiencing something similar but on a Pi Zero W.

That function (hash_net4_test) is not in the latest kernel AFAICT, so I suspect moving to the latest kernel may well fix (or at least change) this error.

FYI. My problem went away after I changed the clock frequency of my Pi Zero W to 900MHZ. i.e. arm_freq=900 within config.txt. So it's possible that it might be that the Pi's cpu is running at the very edge of stability - just a hunch. I don't mean to keep this issue open, however, I wanted to post my solution incase it helps others.
