Hi all,

 I have updated my ubuntu 14.04 LTS server this morning. Until then I
am seeing a lot of errors like:

From an email conversation on our mailing list from Stefan Bader:

  This looks to be introduced by:

      vfs: fix data corruption when blocksize < pagesize for mmaped data
      BugLink: http://bugs.launchpad.net/bugs/1393477
      commit 90a8020278c1598fafd071736a0846b38510309c upstream.

  and fixed by:

    commit f55fefd1a5a339b1bd08c120b93312d6eb64a9fb
    Author: Jan Kara <email address hidden>
    Date: Thu Oct 30 10:35:00 2014 +1100

      mm: Remove false WARN_ON from pagecache_isize_extended()

and:

  Oh, and just for explanation: this is a warning which is wrong. But until it is
  fixed up the only impact is the number of annoying messages in dmesg. The follow
  up change from upstream just removes the warning, nothing else. And since it is
  "only" a warning there is no other effect.

[Brad Figg (brad-figg)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Gábor Lipták (gliptak)]

I'm also seeing this with the same kernel version:

Dec 30 22:09:33 laptop kernel: [143695.572571] CPU: 0 PID: 24084 Comm: URL Classifier Tainted: G W 3.13.0-43-generic #72-Ubuntu

I enabled trusty-proposed as per above, but it didn't offer an updated version of the kernel.

What is the trusty proposed kernel version to be installed?

Thanks

Gábor, you need to explicitly install the "proposed" package : sudo apt-get install linux-image-generic/proposed. In my case it installs 3.13.0-44-generic.

I think the proposed 3.13.0-44 kernel made the call traces go away, but the package didn't build out the dkms correctly, so my nvidia modules do not get loaded.
