Nothing is mounted on that mount point. And this behaviour only
happens with one particular hard drive:
Connect problematic external hard drive into USB port and...
# mount /dev/sdb1 /media
mount: /dev/sdb1 already mounted or /media busy
# umount /media
umount: /media: not mounted
Well, nothing wants to happen there.
Ok, now insert a USB thumbdrive into that USB port...
# mount /dev/sdc1 /media
# umount /media
#
no problem mounting & unmounting the thumbdrive on that mount point.
But with that other hard drive, I have to first do the aforementioned
"dmsetup remove ..." routine, then it will mount & unmount no problem.
Until the next suspend/resume cycle, then it's "dmsetup remove ..."
all over again.
