Public bug reported:
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.
