Title:
  running 'mkfs.xfs' crashes the kernel

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Attempting to create an XFS file system crashed the kernel - I saw a
  kernel stack trace on the screen, and had to power cycle the machine
  after that. I was able to create the file system with one of the 5.x
  kernels and then use it no problem with Bionic, but switching to the
  5.x kernel for good isn't an option.

  
  Expected behaviour:

  Create the file system and print some information about it on screen.
