Structure needs cleaning?

[RUMI Szabolcs]

Hi!

I'm experiencing errors like this:

ls: cannot access 11090000.xhp: Structure needs cleaning

These files were part of an OpenOffice 3.1.0 source tree, and could
not be removed by rm -rf, which was also reporting the above error.

In the dmesg there are errors like this, apparently the same one
for each access attempt:

Is this a known one?
