Dear colleagues,

on most (possibly all, but I'm not fully sure and a bit limited in testing) 
motherboard/controller configuration I've tested so far -current is unable to 
properly attach hot-plugged disks. Sometimes even atacontrol detach/atacontrol 
attach sequence can't bring disk into working state (only reboot does).

One example (today's current/amd64, verbose boot): 

[attach on the fly to eSATA port]

RELENG_6 usually does attach successfully (can't check right now, but hopefully

Any hints?
