The panic is in the zero-copy sockets code. There have been many VM
system changes which may have fixed it. Specifically, Alan Cox
improved the sf_buf system quite a bit between 5.1 and 5.2.
Can you map socow_setup+0xc9 to a source file line number in your
system please? Do
gdb kernel.debug
<...>
(gdb) list *socow_setup+0xc9
BTW, A certain way to prevent this from ever happening is to disable
that code by removing options ZERO_COPY_SOCKETS from your kernel
config file.
Thanks,
Drew
