This is triggered as well on a system without ZERO_COPY_SOCKETS just to clear that bit up. Kostik, I am going to forward you two core.txt.NN files I had generated on a ZFS system that I used chrome on as well. I can trigger this repeatedly from 20-30 minutes of using chrome. Not sure whats going on here but maybe you can shed some light over both issues that seem to be the same thing. I do not mind if you forward these core.txt.NN files to other devs that may be interested and able to help. I still have the kernels for both of these so if more information is needed just let me know.
