Public bug reported:

Since kernel v4.5, the correct parameter to disable USB subsystem
initialization is "usbcore.nousb" always (instead of "nousb" in case the
subsystem is built-in). This was changed by commit 097a9ea0e48 ("usb:
make "nousb" a clear module parameter").

We need to take this into account in kdump-tools, or else we may boot
with USB in kdump even the command-line saying the opposite.

** Affects: makedumpfile (Ubuntu)
     Importance: High
     Assignee: Guilherme G. Piccoli (gpiccoli)
         Status: Confirmed


** Tags: sts

** Package changed: linux (Ubuntu) => makedumpfile (Ubuntu)
