I get a crash on boot with my Fedora xen-4.6.1-3.fc24 packages. This seems
to be related to how it is compiled because the same code compiled under
Fedora 23 works. The boot logs are attached. The address mentioned in the
crash has the code
0xffff82d08023d3c3 <create_bounce_frame+299>:
je 0xffff82d08023e90a <autogen_stubs+4241>
but I have compared it with the Fedora 23 version of create_bounce_frame
and as far as I can see the code is the same, so I am a bit stuck on how
to debug this further.
