Random reboots with 4.13.0-26 on Ubuntu 16.04 LTS

Bug description:
After installing kernel 4.13.0-26 (and 4.13.0-31) we are seeing random
reboots on virtual machines (VSIs) hosted by SoftLayer. The physical
hosts were patched earlier this month but I don't have the details yet
or access to the hypervisors. We noticed 4.13.0-31 was rebooting
frequently and went to 4.13.0-26 instead which was performing better
but still suffering from the random reboots. The VMs still on the old
4.4 kernels haven't had any random reboots at all. We don't have any
intel-microcode package installed, and I'm not sure it would make a
difference for VMs...? We have seen this on both Broadwell and
Haswell systems. The attached apport file is from one of the
Broadwell servers.
