2.4.0 kernel oops from apt-get (dcache.h)

[J.Brown]

After manually deleting the apt-get cache in Debian Linux (2.2), apt-get
consistantly causes a kernel Oops/BUG when installing new packages.

This happens in 2.4.0 (With a few basic patches to fix compilation errors)
and also with the latest PPC bitkeeper tree based off 2.4.1pre1. Dump
below is with the newer kernel, because it's totally stable at the moment
(whereas 2.4.0 final still suffers from other unrelated crashes and
instabilities).

I now have a zombie apt-get process I can't even kill -9..

Also if I try and ls in the /var/cache/apt/archives directory, ls freezes
likewise (no error message, just an unkillable console-attached zombie).

I'm not sure if this is a filesystem or memory management issue - but FYI
anyway, and hoping someone else has encounted a similar problem.

Regards,
