Ding! This sounds awfully like PR kern/9841. Could you please try the
following patch and see if it makes any difference? Please note that I
don't know if this patch will work or not - I'm waiting on someone to
get back from a weekend break to confirm if this is the right "fix" for
the PR.
Ta,
Simon
