Thanks again for your help and hints getting this fixed for me.
I just wanted to send an update that those kernel options seemed to be the ticket to make it stable again. I haven't had it hang since disabling IPSEC, ZERO_COPY_SOCKETS and TCP_SIGNATURE (I wasn't using md5 signatures, having any ipsec sessions or to my knowledge running any applications that'd be using zero copy sockets).
