[Joseph Salisbury <joseph.salisbury@xxxxxxxxxxxxx>]

I built a Trusty test kernel with a revert of commit c6c1f325.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1356558

Can you test that kernel and report back if it has the bug or not?  If
it does still exhibit the bug, I'll have to look at the bisect results
further.

Thanks in advance

Title:
  BUG: soft lockup - CPU stuck for 22s! [md3_raid1]

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  this bug appeared in Ubuntu 14.04, Ubuntu 12.04 didn't show this behavior. 
  I've found a possible predecessor in bug #212684.
  Switching to a recent mainline kernel didn't fix this issue.

  Starting

   $ /usr/share/mdadm/checkarray /dev/md3

  will repeat this behavior.

  /dev/md3 is a LVM PV:

    --- Physical volume ---
    PV Name               /dev/md3
    VG Name               local_vg1
    PV Size               1.36 TiB / not usable 2.25 MiB
    Allocatable           yes 
    PE Size               4.00 MiB
    Total PE              355619
    Free PE               31011
    Allocated PE          324608
