Bug#336153: Fixed in kernel 2.6.19, patch for older kernels available

[Tillmann Steinbrecher <t-st@t-st.org>]

Hi,

this is (was) a well known bug in dm-crypt; numerous people have 
reported it.

It was just fixed by Christophe Saout. See
http://www.spinics.net/lists/dm-crypt/msg00481.html (message from 
dm-crypt mailing list) for short description and patch.

Debian kernel package maintainers: Please apply this patch for debian 
kernels. It's really important due to the amount of data that can 
possibly be lost due to fs corruptions related to this problem.

The bug is also fixed in kernel 2.6.19.

All the best,
Tillmann
