Default Bug#554272: Deferences NULL pointer in xfs

Version: 2.6.31-2

Hi Ben

I still have an issue with xfs in 2.6.31-1-686; but this time it
was not exactly a dereference of a NULL pointer but a failed
"paging request" at "0000341b".

[...]

I think this is still the same bug.

Since this occurs in 2.6.31, the upstream developers will be willing to
look at it. Please report this at <http://bugzilla.kernel.org> under
product 'File System', component 'XFS' and let us know the bug number so
we can track it. You should attach the kernel log that was included in
your mail.

Ben.
