Thanks for taking a look at this and sorry it's taken so long to get
back to you,
I've applied your patch to v2.76 and I'm afraid it doesn't appear to
have solved the problem.

But I do have a little bit more info, I've noticed that this appears
to be linked to router advertisements, every
time I see a truncated packet it's always within milliseconds of a
router advertisement. When I turn off router
advertisements the truncated packets stop happening.
