This is almost surely kernel bug, not userspace one.

It is very old kernel, so hard to say exactly which patches are needed
but my guess is it is very similar to https://bugzilla.redhat.com/show_bug.cgi?id=360151
(note: fixed 2007!) with upstream patch
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=512875bd9661368da6f993205a61213b79ba1df0

(But there can more patches, this is really old and someone need
to do proper analysis what is going here.)
