For the stable distribution (woody) this problem has been fixed in version 2.4.17-0.020226.2.woody3 the mips and mipsel architectures.

For the unstable distribution (sid) this problem will be fixed soon with newly uploaded packages.

We recommend that you upgrade your kernel packages. This problem has been fixed in the upstream version 2.4.24 as well.

Upgrade Instructions - --------------------

wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
