--- Comment #1 from David Smith <dsmith at redhat dot com> ---
Looks like this was a s390x kprobes bug. The fix was first backported to
kernel-3.10.0-155.el7. The kernel crashed after it tried to emulate the "lgrl"
instruction.

The fix was composed of the following upstream kernel patches:

c802d64a356b5cf349121ac4c5e005f037ce548d
af96397de8600232effbff43dc8b4ca20ddc02b1
63c40436a1afc837f3ace6b5a39c547bc91c20bc

It doesn't look like there is a way for systemtap to work around this kernel
bug, so I'm going to close it.
