Comment 20 for bug 1825395

I've come up with a theory that I think matches what I observe. It seems that my laptop gets into the bad state if I suspend too quickly after hot unplug from thunderbolt. If I wait long enough after hot unplug that all the thunderbolt devices are fully removed, then the system remains fine. If I suspend while cleanup is still going on, then upon resume the system confuses itself trying to deal with devices that are no longer there (and that never get cleaned up).
