Package: linux-image-2.6.32-5-vserver-amd64
Version: 2.6.32-41
In a vserver based virtual machine /proc/meminfo shows incorrect values of Buffers memory: 
root@node2:~# uname -a
Linux node2 2.6.32-5-vserver-amd64 #1 SMP Mon Jan 16 19:31:31 UTC 2012 x86_64 GNU/Linux 
root@node2:~# vserver vm enter
root@vm:/# cat /proc/meminfo |grep Buffers
Buffers:           80040 kB
root@vm:/#
And as a result 'free' command invoked in this virtual machine gives very strange values: 
vm # free
root@vm:/# free -k
total used free shared buffers cached 
Mem:       4000000       7868    3992132          0         79896          0
-/+ buffers/cache: 18014398509409956    4072028
Swap:            0          0          0
root@vm:/#
In this output the amount of used memory - buffers/cache is bigger than I'm able to install in a physicall host:)
Here is a patch to resolve this problem - http://comments.gmane.org/gmane.linux.vserver/17878
I applied this patch to 2.6.32-5-vserver kernel sources, compiled the kernel, and now Buffers value of /proc/meminfo 
is 0:
root@vm:/# free -k
            total       used       free     shared    buffers     cached
Mem:       4000000       5724    3994276          0          0          0
-/+ buffers/cache:       5724    3994276
Swap:            0          0          0
root@vm:/# cat /proc/meminfo |grep Buffers
Buffers:               0 kB
root@vm:/#

Version: 3.4.1-1~experimental.1+rm

Debian 6.0 Long Term Support has ended, and the 'linux-2.6' source
package will no longer be updated.  This bug was reassigned to the
'linux' source package earlier today, but I am now closing it on the
assumption that it does not affect the kernel versions in newer Debian
releases.

If you can still reproduce this bug in a newer release, please reopen
the bug report and reassign it to 'src:linux' and the affected version
of the package.  You can find the package version for the running
kernel by running:

    uname -v

or the versions of all installed kernel packages by running:

    dpkg -l 'linux-image-[34]*' | grep ^.i

and looking at the third column.

I apologise that we weren't able to provide a specific resolution for
this bug.

Ben.
