Package: linux-modules-2.6.26-2-xen-amd64
Version: 2.6.26-24
Severity: critical
Justification: breaks the whole system


We're using a two node cluster with drbd and ocfs2 as filesystem, exported 
via NFS to some webnodes.  The nfs clients use the nordirplus mount option.
We had the reboot one of the cluster nodes due to the following kernel BUG.  
Looks like debian bug #506950 to me.  Upstream has a fix:

http://www.mail-archive.com/ocfs2-users@oss.oracle.com/msg03855.html

Here's the BUG:

Sorry for the very slow response.  I agree that they look the same.

Thanks for digging that up.  For reference, that's

  6ca497a83e59 ocfs2: fix rare stale inode errors when exporting via nfs

which was part of 2.6.30-rc1.  Closing optimistically.  If you learn
more, please don't hesitate to let us know.

Ciao,
Jonathan
