The old stable distribution (sarge) is not affected by this problem.

For the stable distribution (etch), this problem has been fixed in
version 2.6.18.dfsg.1-18etch1.

In addition to these fixes, this update also incorporates changes from
the upcoming point release of the stable distribution.

Some architecture builds were not yet available at the time of
DSA-1494-1. This update to DSA-1494 provides linux-2.6 packages for
these remaining architectures, as well as additional binary packages
that are built from source code provided by linux-2.6."
