Description of problem:

Trying rawhide kernel 4.5.0-0.rc2.git1.1.fc24.i686+PAE, I found this in dmesg:

[  108.223030] systemd-udevd/1827 just changed the state of lock:

[  108.223030] but this lock took another, HARDIRQ-unsafe lock in the past:
[  108.223030]  (&(&list->lock)->rlock#2){+.-...}
               
               and interrupts could create inverse lock ordering between them.
