unmounting a volume

What do you do when you want to unmount a volume, but its BUSY by some nonexistant process?

I had a USB drive mounted and the drive went into suspend. It doesn't wake up properly with this kernel and unmounting hangs the command line. Syncing hangs too. Unmounting with the -f option tells me umount is also busy?!

root@dattaway dattaway # umount /v -f

umount2: Device or resource busy umount: /v: device is busy

root@dattaway dattaway # fuser /v /v:

The only thing I know how to do at this point is to guess and start killing processes all the way to init. There has to be a better way.
