Please attach the patch you mentioned.

Is this a kernel patch, or a patch to thinkfinger. Any way to fix this at the thinkfinger level rather than the kernel level?

Here is the patch.
AFAIK this is a kernel bug in 2.6.28.0 and is supposed to be patched into one of the -stable releases.

What is the source of the patch? If it is upstream, mailing lists etc, please post a link to it.
