the umount command is still not finished, I copied a mere 320 MB file to a VFAT USB Thumbdrive using tz and time to monitor how long it takes to umount after the copying:

Looking into recent entries concerning the device ( /mnt/sdd1 ) in /var/log/messages I realized for some unknown reason the other two external devices I mounted and umounted are mentioned (sdc1 and sde1) but not sdd1!

using mount to tell me what devices are mounted minus sda* and sdb* using this one-liner:

And what kind of limbo state is sdd1 currently in?
It's LED is blinking meaning there is a read or read/write operation going on, but like I said above: when the umount is not finished after several hours it never will finish.
Executing sync also seems to never be able to finish most likely due to the same sdd device:

D uninterruptible sleep (usually IO)

Any ideas?

Update
since the 1st approach of going into suspend failed (system came back after approx 10 seconds of black screen) I plugged out the offending USB thumbdrive but the system crashed at 2nd suspend anyway (the kind of crash where not even REISUB was working)
But the fsck on all Unix file systems during boot was okay, and the fsck.vfat on the USB thumbdrive did require some minor cleanup, and the md5sum of the copied 320 MB file was wrong, so I simply deleted it. Good luck no harm was done because of the system crash.
