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.
