i built and installed the module from those sources but the problem
still isn't fixed. also modinfo on the new module claims to be version
1.47 while the changelog contains changes up to 1.48.

i have 2 files available for download, one pcap-dump of the failure and
the dmesg-output.

the problem occured when the client tried to access the directory named
'tchibo/reisen/de/01_kundeneingang/tchibo_shop_zubehoer/070403_polaroids_winter_sommer'.


you can download the files at the following locations:

http://www.arles-electrique.de/cifs-problem.pcap
http://www.arles-electrique.de/cifs.dmesg

hope it's useful of some kind.

regards,

alexander
