For future references, the issue was the kernel version 4.4.118, upgraded and the problem was gone.
A bit of Unix sysadmin lore that isn't as widely advertised as it once was (because, thankfully, it comes up far less often than it used to): there are only three reasons why a process would remain in an uninterruptible sleep for more than a few milliseconds: an abnormally slow storage peripheral (e.g. a tape drive being rewound, or a hard drive that's about to fail), a network file server that isn't responding to messages, or a kernel bug.
