We are looking into this.

=======================
I saw this in -rc5-mm4 also.
I couldn't find a contact address in MAINTAINERS, so I've CC'd the
two authors listed on top of ima_create_htable.c , as well as the
first submitter of the IMA stuff I found in my LKML archive.
As an aside, this computer does have (some sort of) TPM chip, but
the driver is built as a module, and not loaded at this point (not a
worry for me, I don't intend to use it).

Joseph,
we cannot reproduce the BUG you report. We have identified a potential
source (spinlock around mutex_init). I have attached a small patch that
removes this lock from the initialization of the hash table. I have
tested the patch but I cannot verify if this resolves the problem you
are seeing.
If you can reproduce the problem, would you mind to apply this patch and
let us know if this solves the problem?
Thanks

The BUG message no longer appears with this patch applied. It was 100%
reproducible before, so I think this fixed it.
Thanks!

ok, the spinlock in there was unneeded anwyay.
But I think this is a lockdep shortcoming - there's nothing wrong with
doing mutex_init() inside spin_lock().
debug_mutex_init() is trying to work out whether we're initialising
an already held mutex. This has nothing to do with the spinlock
which we're holding. Perhaps debug_check_no_locks_freed() simply
went wrong.
For Ingo - this:

- Lots of x86 updates
- This is a 25MB diff against mainline, which is rather large.
Boilerplate:
- See the `hot-fixes' directory for any important updates to this patchset.
- To fetch an -mm tree using git, use (for example)
git-fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git tag v2.6.16-rc2-mm1
git-checkout -b local-v2.6.16-rc2-mm1 v2.6.16-rc2-mm1
- -mm kernel commit activity can be reviewed by subscribing to the
mm-commits mailing list.
echo "subscribe mm-commits" | mail majordomo@vger.kernel.org
- If you hit a bug in -mm and it is not obvious which patch caused it, it is
most valuable if you can perform a bisection search to identify which patch
introduced the bug. Instructions for this process are at
http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt
But beware that this process takes some time (around ten rebuilds and
reboots), so consider reporting the bug first and if we cannot immediately
identify the faulty patch, then perform the bisection search.
- When reporting bugs, please try to Cc: the relevant maintainer and mailing
list on any email.
- When reporting bugs in this kernel via email, please also rewrite the
email Subject: in some manner to reflect the nature of the bug. Some
developers filter by Subject: when looking for messages to read.
- Occasional snapshots of the -mm lineup are uploaded to
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/mm/ and are announced on
the mm-commits list.

I'm seeing this while booting:
ima (ima_init): No TPM chip found(rc = -19), activating TPM-bypass!
=========================
[ BUG: held lock freed! ]
-------------------------
swapper/1 is freeing memory c04c7660-c04c76a3, with a lock still held there!
(ima_queue_lock){--..}, at: [<c0202710>] ima_create_htable+0x10/0x90
1 lock held by swapper/1:
#0: (ima_queue_lock){--..}, at: [<c0202710>] ima_create_htable+0x10/0x90

[<c010532f>] kernel_thread_helper+0x7/0x18
=======================
I saw this in -rc5-mm4 also.
I couldn't find a contact address in MAINTAINERS, so I've CC'd the
two authors listed on top of ima_create_htable.c , as well as the
first submitter of the IMA stuff I found in my LKML archive.
As an aside, this computer does have (some sort of) TPM chip, but
the driver is built as a module, and not loaded at this point (not a
worry for me, I don't intend to use it).
