** Description changed:
I have been using Intel FakeRAID on an Asus Z77 motherboard on Kubuntu
12.04 for months. I'm using the MDADM version and not DMRAID. It has
been working fine other than a couple minor issues with clean shutdowns
that I fixed by tweaking a couple of the scripts under /etc.
I upgraded to the latest Linux kernel (3.2.0-51) and my FakeRAID stopped
working, probably because auto-detection failed to see the RAID array.
Everything works fine with the previous kernel image, 3.2.0-49.
Here is /proc/mdstat with the 3.2.0-49 generic kernel image:
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4]
[raid10]
md126 : active raid1 sdb[1] sdc[0]
976758784 blocks super external:/md127/0 [2/2] [UU]
md127 : inactive sdb[1](S) sdc[0](S)
6306 blocks super external:imsm
The /proc/mdstat file is empty (other than listing personalities) in
3.2.0-51. Note that the sdb and sdc drives are recognized by 3.2.0-51,
and their partition tables look reasonable, so I don't see any issues
with 3.2.0-51 actually seeing the physical drives. The problem appears
to be that the MD driver doesn't detect the external RAID (aka 'imsm')
metadata created by Intel fakeraid.
Here's the additional data requested for new bug reports:
lsb_release -rd
Description: Ubuntu 12.04.2 LTS
Release: 12.04
apt-cache policy linux-image-3.2.0-51-generic

FWIW, here's the apt-cache data on the previous kernel where fakeraid
worked correctly:
apt-cache policy linux-image-3.2.0-49-generic
linux-image-3.2.0-49-generic:

I will attach the kernel.log for booting 3.2.0-49 and 3.2.0-51. I've
looked at them and all I see is that 3.2.0-49 'binds' the RAID array
components and 3.2.0-51 doesn't. Here's a snippet from 3.2.0-49 where
it starts my RAID. This is absent in 3.2.0-51.

- Any suggestions on how to troubleshoot and/or fix this? There's no point
- bisecting the kernel images given the regression has just appeared in
- 3.2.0-51 and, AFAIK, there was never a release of a '3.2.0-50' kernel.
