Thanks. Yes, have seen that one too. > Is it the same messages that you are seeing in Xenial ? There are a handful of different MSRs mentioned, and these are not always the same across each "burst" of unhandled rdmsr log messages. After a bit of further head-scratching we think the crashes are actually occurring due to kernel panics following SLUB memory allocation failures related to heavy Lustre workloads. We've now started patching Lustre clients for that and seeing the guest crash stop. At this point I don't have any idea why this seems to correspond with rdmsr attempts though (and actually it looks like the rdmsr happens just prior to the SLUB failures). -- Cheers, ~Blairo _______________________________________________ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
