I get the same messages with my external USB drive from time to time
(interestingly also GBDE encrypted).

Nov 20 02:03:30 haakonia kernel: g_vfs_done():da3s2c.bde[WRITE(offset=383341297664, length=65536)]error = 1

The message repeats every 30 seconds and trying to unmount the file
system fails.  When I try to shut the system down, the message appears
n > 50 times followed by a panic.

Is it possible that the system tries to write on a bad sector and
consequently fails (provided that the on-disk sector remapping also
fails)?

The SMART output of the drive looks ok.
