Please could you share some logs and more details about the crashes and
stalls? At the moment there's not much we can do with this report :/
Ideally, we'd have steps to reproduce the issue, but it seems that you
don't have a reliable method for that.
One other thing you could try is removing the WFE from our cmpwait
implementation in case you have a CPU erratum in that area.
