You should get the filename, e.g.:

$ kpsewhich st10-03_M1_with_L160_LED.tex

This is very helpful as kpsewhich has lots of debugging support.

pdftex uses mmap2 for lots of files -- you need to look for
lines like:

entering extended mode
open("st10-03_M1_with_L160_LED.tex", O_RDONLY) = 3

I installed Samba on my Ubuntu 9.10 box and mounted my home directory
using cifs on the same machine and can't reproduce the error.

$ df -t cifs
Filesystem           1K-blocks      Used Available Use% Mounted on

$ pwd
$ cat st10-03_M1_with_L160_LED.tex
A quick brown fox jumps over the lazy dog.
$ latex st10-03_M1_with_L160_LED.tex

In my test using CTAN TL2009 the tex source file is not memory mapped.
Your version may behave differently, but the kpathsea problem suggests
that the problem is elsewhere.
