Comment (by ithamar):

 I have seen the same KDL as the last picture on removal of a R/W mounted
 BFS partition on a USB disk. I suspect somehow the USB device is already
 gone when the sync call is made, and BlockWriter does a panic() on not
 being able to write some blocks back to the device.

 I'm looking into the USB removal case, I'll post my findings here.
