This happens on all kernels up to 4.7. Sorry, it happens earlier than ethernet coming up or my storage, so I can't use netconsole or other text dumps: https://goo.gl/photos/ubsi6maZXsjkevYY7 Looks like the warning happens on the registration of one of my bcache, but I can't tell which one or why. Does the trace give any hints? (please ignore the load modules errors below, different issue) Thanks, Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
