Hide specific error messages at shutdown

I see these messages when I shut down my computers.

blk_update_request: I/O error, dev loop0, sector 0 op 0x1:(WRITE)
flags 0x800 phys-seg 0 prio class 0

This happens only when I have a Vera Crypt volume open in an NTFS Pendrive.
If I close the volume before shut down, there are no error messages.
This started after a big update last December.
Before this update, there were no error messages.
The fact is that I see error messages but nothing seems to work wrong.
So my question is … Is there a way to hide these specific error messages when I shut down my computers?
They are very annoying.
Thanks a lot in advance!

BTW … I have asked about this problem in the Vera Crypt forums but nobody answered.

You give your own answer:

Simple enough solution, don’t you think? :roll_eyes:

Thanks for your answer but I don’t think so.
It’s like having to unmount every pendrive before shutting down the computer.
If you forget to unmount the pendrive you would see several error messages at shut down.
Before the huge Manjaro update of 2020.12.30, I didn’t have to close anything. It was done automatically.
