Jaon, the next step is to fully reverse commit bisect from kernel 4.4 to
4.7-rc2 in order to identify the last bad commit, followed immediately
by the first good one. Once this good commit has been identified, it may
be reviewed for backporting. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Also, the kernel release names are irrelevant for the purposes of
bisecting.

After the fix commit (not kernel version) has been identified, then
please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  The device on /dev/sdx is not created when inserting new devices

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am on kubuntu xenial (upgraded from 15.10), from a couple of weeks I noticed that the pendrives i insert to my computer are detected but the devices under /dev are no longer created.
  I if reboot the pc with the pendrive already plugged in it works without issues. I'm suspecting from udev because of this text in syslog (full output in the summary)

  Jun  7 15:02:55 pc systemd-udevd[24747]: inotify_add_watch(9,
  /dev/sdb, 10) failed: No such file or directory

  I'm up to date on all the packages
  - linux-image-4.4.0-22-generic
  - udev - 229-4ubuntu6
