The only calls I see are in the scan when the devices is added and in the re-scan. It should not be consuming the scsi_eh thread unless some type of udev events keeps happening. Would be good to get some cat /proc//stack of the scsi_eh threads if they are constantly consuming CPUY I will try reproduce and try figure out what is going on here.
