Title:
  Kernel oops - blk_update_request: I/O error when running udisks2
  force_test_removal test

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  We noticed that the udisks2 autopkgtest is failing on i386 in the
  "forced removal" test, for example

    https://jenkins.qa.ubuntu.com/job/wily-adt-
  udisks2/ARCH=i386,label=adt/55/console

  I reproduced this locally, on this kernel

  ubuntu@autopkgtest:~$ uname -a
  Linux autopkgtest 4.1.0-2-generic #2-Ubuntu SMP Wed Jul 22 18:17:34 UTC 2015 i686 i686 i686 GNU/Linux

  and got the following spewed to console

  To reproduce, do something like this:

  $ adt-buildvm-ubuntu-cloud -r wily -a i386 # download a cloud image, fettle it a bit to be more useful
  $ qemu-system-i386 -m 2048 -net user -net nic,model=virtio -enable-kvm -nographic adt-wily*
  # login with ubuntu/ubuntu

  # apt-get update
  # apt-get dist-upgrade
  $ apt-get source udisks2
  $ cd udisks2-*
  $ cat debian/tests/control # install the test-deps
  # debian/tests/upstream-system # runs the testsuite, when it gets to test_force_removal you should see this bug. the testsuite hangs too.
