Subject: [v4.0][v4.1][v4.2][Regression] tpm: fix raciness of PPI interface lookup
Date: Mon, 14 Sep 2015 17:36:07 -0400	[thread overview]
Message-ID: <55F73DC7.4070007@canonical.com> (raw)

Hi Jarkko,

A kernel bug report was opened against Ubuntu [0] and in bugzilla[1].  A
kernel bisect was performed, and it identified the following commit as
the first bad commit:

commit 0dc553652102c55a43eb1ab52e2049e478469f53
Author: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com>
Date:   Fri Dec 12 11:46:35 2014 -0800

    tpm: fix raciness of PPI interface lookup


The regression was introduced as of v4.0-rc1.

I was hoping to get your feedback, since you are the patch author.  Do
you think gathering any additional data will help diagnose this issue,
or would it be best to submit a revert request?  An issue with the
revert request is that it would also require reverting several other
commits that came after this commit or a backport of the revert.
    

Thanks,
    
Joe
