Comment # 72 on bug 1055641 from Neil Rickert

Just a note.  After recent Tumbleweed updates, I am no longer seeing those
"Command failed" messages.

However, I am now sometimes getting messages:

 remove ioctl for seagate1-root1 failed  device or resource busy

That's approximate wording.  The messages go past too fast to read them
clearly.  I'll note that this is evidently referring to the logical volume for
the root file system (which is part of an encrypted LVM).  I'll also note that
if I check after the shutdown has completed, that file system seems to be
clean.
