Ice, a machine which holds the /mail partition as well as mail, mx2, and some private virtual machines, spontaneously rebooted today.

     There would appear to be some stability issues in 5.7 yet.  I suspect these related to NFS as both ice and iglulik export major NFS partitions used by the rest of the machines here and the physical hosts which do not as well as the virtual machines which do not have all been stable.

     There were some major changes in the NFS v4.2 code in 5.7 which I hope, when adequately debugged, will result in better reliability so I’m not giving up on this kernel just yet but will keep up with point releases and try to identify in greater detail what is failing.

     Everything is back in service but I still need to check all the mounts.
