Default Bug #506586 kernel crash on accessing remote cifs

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

[Please cc me, I am not subscribed to debian-kernel]

I have tried to further investigate the problem leading to a system
freeze on connection to a remote cifs share.

On one occasion I was able to take a screen shot. Unfortunately, my mail
with the attached screen shot (100 kb) did not make it to the bts or the
list. (Is there a prefered way of handling this?)

On another occasion I found the excerpts in syslog, that are attached.
I'm not sure if this is really relevant, though, since I could not
reproduce the syslog entries or the on screen output of the panic.

I am told that the remote system that kills my debian box on connection
is running a Netapp 6070 with Data OnTAP 7.2.4 (what ever that is).

As far as I could tell, the problem does not occur, if the remote system
is accessed with the fuse tools (kde konqueror). Unfortunately, these
lack some of the functionality I require (synchronisation with unison or
rsync).

I don't know how to proceed from here. I could try to capture and post a
trace of the network traffic leading to the kernel crash, if that is
considered useful.

I'm not sure if that has any security relevance (system freeze on
connecting to remote computer).

Cheers,

Johannes
