the hot-add/hot-remove workaround was performed on a mishmash of hosts where this has crept up. the majority were precise hosts w/a 3.5.0 hwe kernel. one was trusty w/3.13.0-37-generic and the remainder are running locally built kernels from linux-source 3.13.0-35.62 w/the patch from lp#1368991 applied (these are the hosts i have to wait for reboot).
