Error. So when resetting the capi adapter through sysfs, make sure the PSL cache is flushed. It won't help if there are any active Process Elements on the card, as the cache would likely get new dirty cache lines immediately, but if resetting an idle adapter, it should avoid any bad surprises from data left over from terminated Process Elements.
