I can also confirm that all the kernels have this bug fixed (precise
3.2.0-93.133, trusty 3.13.0-67.110 and lts-utopic 3.16.0-52.71~14.04.1).

Title:
Something in the Kernel crashes
Based on the duplicate bug that I raised, 1509666, I can confirm that with
kernel 3.13.0-67-generic loaded, the bug I saw (relating to mounting in OSX) is
solved.
I have added the verification-done-trusty tag.

Thanks @marius888.
Yes, behaviour and the log-messages were exactly the same under 3.16.0-51, as
you can see in marius' stacktrace.
We were both facing this using vagrant-built virtualbox-machines with
NFS-shares on Lenovo Thinkpads W520/30.
I will try to reproduce it also on lts-vivid
You are right, no problems, neither with 3.19.0-31 nor with 3.19.0-30.

Thank you. Andreas, I believe vivid is not impacted by this bug. Looks
like the issue has been reported to the stable mailing-list:
http://thread.gmane.org/gmane.linux.kernel.stable/153526
Thank you all for reporting and testing.
** Also affects: linux (Ubuntu Trusty)
Importance: Undecided
I have kernel 3.16.0-51 and the issue is the same. Going back to
3.16.0-50 solves the problem.

Yes, this patch solves the issue for me. Mount command works as expected

Something in the Kernel crashes when I try to mount via NFS
Status in linux package in Ubuntu:
Thanks a lot for testing, Andreas. Regarding the utopic kernel
(3.16.0-51) issue you also refer, are you absolutely sure it's the
same problem? Can you please share the kernel log?
I'm assuming you're running trusty lts-utopic for this, so in the
morning I will try to reproduce it (I was able
I can confirm this. The same behaviour occurs with the latest utopic-kernel
(3.16.0-51). Going back to 3.16.0-50 solves the problem.
This happens only when using nfs v3 over UDP like so:
mount -o 'vers=3,udp' 192.168.56.1:'/home/andreas/somefolder' /mnt/nfs-
somefolder
Using NFS v4 and/or TCP
We do suspect of a backport of upstream commit 89c22d8c3b27 ("net: Fix
skb csum races when peeking") (which is 2dde51aa5339 in the trusty git
tree). I've built a test kernel with this commit reverted on top of
3.13.0-66.108 and uploaded it here:
Would it be possible for you to test the latest upstream stable kernel?
Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the
latest v3.13 stable kernel[0].
