I have tried with kernel 4.14 and with kernel 4.19 from the 19 branch and also removing the nf_conntrack_rtcache module, but the result is the same.
There are times that I see no BUG at all, others where I see it appear between 1 and several times. I use several docker containers and depending on the races, sometimes everything launches well and afterwards (if I don't play with new docker instances) it is 100% stable whereas other times I have to reboot up to 3 or even 5 times for everything to work reliably.

I'm seeing this issue on master built for x86-64, it's been happening since I started using this x86-64 machine around December.
