This is triggered as well on a system without ZERO_COPY_SOCKETS just to
clear that bit up.
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.
