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. |
