[Bug 209402] Re: Samba shares die with input/output error

[Peter Funk]

On a system with kernel version:
Linux version 2.6.24-26-server (buildd at vernadsky) (gcc version 4.2.4 (Ubuntu 4.2.4-1ubuntu3)) #1 SMP Tue Dec 1 19:19:20 UTC 2009
and several CIFS mounted volumes on this Ubuntu 8.04 LTS server something similar has happened:

Mar  1 23:17:43 ac51901 kernel: [281431.960782]  CIFS VFS: Error 0xffffff90 on cifs_get_inode_info in lookup of \.Trash-1000

Mar  1 23:17:46 ac51901 kernel: [281435.046587]  CIFS VFS: Error 0xffffff90 on cifs_get_inode_info in lookup of \.Trash

I've got here by googling this particular error message, which 
was repeating over and over again for quite some time until 
after a while the following happened: 
Mar  1 23:36:23 ac51901 kernel: [282549.896912] swapper: page allocation failure. order:1, mode:0x4020
Mar  1 23:36:23 ac51901 kernel: [282549.896923] Pid: 0, comm: swapper Not tainted 2.6.24-26-server #1
Mar  1 23:36:23 ac51901 kernel: [282549.896949]  [nfs:__alloc_pages+0x2ab/0x380] __alloc_pages+0x2ab/0x380
...

Since users complained about "the system feeling frozen" it was 
rebooted at 23:55 and the effect has not been observed again since.
I it matters: the windows shares are mounted using autofs and cifs
with according to /pro/mounts the following options:

rw,mand,relatime,unc=\\WIN2000BOX\SHARENAME,username=operator,uid=1000,gid=100,rsize=16384,wsize=57344
0 0

If there is anything I can do to track this down let my know.

Regards, Peter.
