Here's at least two that makes the 2.6.10-4 go boom.

http://bacchus.bel.fi/MI1.hdf.gz (2.2 MB)
http://bacchus.bel.fi/WB3.hdf.gz (4.6 MB)

I can get the oops to happen on the MI1 but not with WB3 on Debian's 2.6.8-1.

I was not able to find any .ADF files (which are 900 kB disk images) immediately
that crashed. I'm still pretty sure that initially when I investigated the scope
of the crashes I was able to get an .ADF or two to crash, too. Right now they
seem to work.

Here's how I make it crash:

% gunzip WB3.hdf.gz
% sudo mount WB3.hdf /mnt/tmp -o loop -t affs
% cd /mnt/tmp
% sudo cat **/* > /dev/null
Segmentation violation

In the logs, there's an oops now of the type I reported previous. Strace of the
cat reveals the following:

...
open("Devs.info", O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0600, st_size=632, ...}) = 0
read(3, <unfinished ...>
+++ killed by SIGSEGV +++

Boom! It died right at read().
