How reproducible:

Steps to Reproduce:
1.mount a smb drive
3.stop using it
4.use it some more

Actual Results:  smb_trans2_request: result=-104, setting invalid

Got the exact same oops again. The autoload theory doesn't seem to hold as I had
just accessed the root of the smb share and done an ls there and got the result
(just after booting). Then I cd-ed into a directory and did ls again and got the
oops. This only happens on 2.4.9-31, not 2.4.9-13.
Comment 2 Arjan van de Ven 2002-03-11 08:27:14 EST
Can you try the 2.4.9-31.1 kernel at

it has a fix for an smbfs oops
Comment 3 Need Real Name 2002-03-11 09:15:09 EST
So far so good. Not been using it for long though but it didn't usually
take long to get an oops.

Got this in my dmesg:
smb_proc_readdir_long: name=<filename removed>:2568sla_files\*, result=-2,
rcls=1, err=2
Comment 4 Bugzilla owner 2004-09-30 11:39:24 EDT
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
