Thinkpad x230, behavior began after a sysupdate. I can't say the exact 
date it was updating from, but some time during the "Golden Age of 
Ballooning" period. Now every time I use fshalt I get a panic. The disk 
is an mSATA SSD running hjfs.

Below is my sysinfo, attached is a picture of the error output on 
screen.
