Instability during large transfers

[Jason A. Donenfeld]

Hey Samuel,

Thanks very much for the excellent debugging output. I'll try to
reproduce this as well on my systems.

The stack trace does indicate that the OOPS is happening in padata,
not in wireguard, so I wonder if this is some bug caused either by
grsecurity or by something else that was then fixed, but since your
kernel is a bit old (4.7.10) maybe the fix didn't make it. In either
case, I'll try to reproduce on that kernel and on newer kernels and
will get back to you.

I presume you have most PaX options turned on?

Thanks,
Jason
