Joseph,
thank you for posting this problem. I cannot reconstruct it on my machine.
Could you tell us which kernel configuration you used (drivers/char/tpm
and security settings) ?
Does it disappear when IMA is disabled in the kernel config?
Reiner
Here's the .config I forgot to attach the first time -- sorry!

I've found that disabling CONFIG_SYSFS_DEPRECATED makes the
BUG message go away; maybe that's what you're missing?
I've also attached my .config -- but it has lots of stuff turned
on, so it may be faster to try flipping CONFIG_SYSFS_DEPRECATED on a
slimmer config, if you'd like.
Disabling IMA doesn't change the message; it's still there.
Thanks!

Thank you very much for these helpful details. We are working on a
solution.
