We should try some of the 3.13 release candidates since 3.12 final does
not have the bug.

Can you test the following kernels and report back? We are looking for
the first kernel version that exhibits this bug:


v3.13-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc3-trusty/

If v3.13-rc3 does not exhibit the bug then test v3.13-rc6:
v3.13-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc6-trusty/

If v3.13-rc3 does exhibit the bug then test v3.13-rc2:
v3.13-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc2-trusty

You don't have to test every kernel, just up until the kernel that first
has this bug.

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
