It means that some process got signalled while trying to perform an 'ioctl' on an md device that was busy in some way that prevented any ioctl. However md devices are not 'busy' in this way for extended periods of time, so getting interrupted while waiting for the lock would be quite unusual. The ioctl in question is number 4705, or 0x1261. This means that '0x12' group of ioctls, number 0x61. All md ioctls are group '9', so it isn't an md ioctl. It might help to know what command was causing it... If you feel adventurous, you could edit drivers/md/md.c, find where it prints that message, and get it to print the string current->comm as well. If not, probably don't worry about it. I suspect it is harmless, though it is puzzling.
