samba - Feb 2012 - system freeze with message CIFS VFS: Unexpected lookup error -88

Hi everyone,

I have had a few system freezes in the recent months (debian squeeze 
with vmlinuz-2.6.32-5-686-bigmem), with the following message in dmesg :

CIFS VFS: Unexpected lookup error -88
CIFS VFS: Send error in SessSetup = -88

It is the same symptoms as in the redhat bugzilla :

https://bugzilla.redhat.com/show_bug.cgi?id=711400

It it mentionned that it is patched in redhat kernel 
kernel-2.6.32-170.el6, but I have not found any information if that 
patch was sent upstream, and if yes, in which cifs module version.

If anyone has information on this one, I'd be glad to hear.

Cheers,

Denis Cardon

Hai, 

Which version of samba are your running, the debian stable version? 
if not, try the 2.6.39 kernel from backports. 


vi /etc/apt/sources.list.d/debian-backports.list
add : 
deb http://backports.debian.org/debian-backports squeeze-backports main

apt-get update
apt-get install -t squeeze-backports linux-image-2.6.39-bpo.2-amd64

and check again if the error is there.

Louis
