Still present as of 2.6.31-rc2-00257-gc2cc49a.

I tried reverting 3f09df70e3a33590ae5a97b8a15486d3711c7065 ("NFS: Ensure
we always hold the BKL when dereferencing inode->i_flock") to no avail,
so I guess it's bisection time.

Attached in case it is useful is dmesg from boot wherein the following
occurs: 1) I trigger the problem by opening a file on NFS with emacs 2)
I trigger sysrq-T 3) the softlockup warnings fire 4) I trigger sysrq-T
again.

After this all occurred I was still able to perform operations on the
NFS mount, including playing a movie stored there.
