Yes, that appears to be the problem.  Under Windows, the phone
shows 3 filesystems and the problematic one reports CDFS.  I 
should note that I've plugged this phone into this laptop
for a few years without any issues.  I unfortunately updated
a circa Aug 2013 freebsd-current to a week old -current.  It
has not been a pleasant experience.  Unzipping or untarring
a large compressed archive onto a USB mounted hard drive
renders the system unusable for minutes at a time. unzip
and bsdtar are stuck in getblk or wdrain for 30 to 60
seconds.  System recovers for a few seconds then get stuck
again.  Rinse and repeat.  I'm not sure if it is a UFS2
or USB or some other change.
