Kernel Trace at boot on fs/xfs/linux-2.6/xfs_aops.c:1008

[Matteo Chesi]

Hi,

I am Matteo Chesi,

I am sorry to bother you, it's the first time I have an issue with XFS
and I don't know if it's correct to send you this kind of support request.

My issue is that I receive a kernel trace like this at every boot of my
machine:

My kernel is: 2.6.32-504.16.2.el6.x86_64 (from a just updated Centos 6.6)

I would like to understand what it could be the issue.

Thanks In Advance for any answer,

Best Regards,
