There have been _hundreds of changes_ to the tty core since 3.2, many
to specifically fix the type of error reported.
Very few of these changes are trivial; there are at least a dozen patchsets
with 10 or more patches. I doubt these will ever be backported to -stable;
the changes are just too extensive.
It makes sense to establish if these changes have indeed fixed the observed
error already or if more in-depth debugging is necessary to uncover the root
cause.

Peter Hurley
