Public bug reported:
When copying a large number of files or copying files over 100 GB of
process hangs, and the logs I get the following error:

It does not matter whether the copying (read / write) is the partition
EXT3, EXT4, XFS, NTFS. The problem occurs after a few tens minutes, and
ultimately results in the need to reboot the machine.
