Currently there is a way for userland to determine if a hotplug event
they receive is due to an EEH slot isolation event. It's not very
pretty and requires the rtas_errd daemon to be running.
The RTAS event generated from the EEH event is logged to
/var/log/platform by rtas_errd. Userland scripts would have to search
the file for a recent EEH event matching their device to make this
determination. This isn't as nice as a direct notification but is what
we have at this point.
