Title:
Random reboots with 4.13.0-26 on Ubuntu 16.04 LTS
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Artful:
Won't Fix
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.
