XFS and LVM problem

[Jonathan Selander <jonathan.selander@xxxxxxxxxxxx>]

Hi,

I have a quite large (~1.2TB) LVM volume on which I use an XFS 
filesystem. However, I noticed that after a couple of days of usage, the 
filesystem dies and has to be remounted to be used again. I don't get 
any hardware related errors in dmesg, all I get is this:

Any idea what could be wrong? This is driving me quite mad. I run Debian 
3.1 with a vanilla 2.6.12.2 kernel.
