Kernel oops when using XFS

Hey all,
I’m using XFS on a Ubuntu 14.04.1 x84_64 machine and getting kernel oops
messages from the XFS module almost daily.
My machine is a 6-core Core-i7 with 24GB RAM, an mdadm software raid5 over
4 disks with an XFS fs on it.
Here is a typical error message:
[Wed Jul 1 07:14:30 2015] XFS (md1p3): Access to block zero in inode

I have gathered some information that I hope can help figure out what the
problem is. FYI, this sort of problem also happened when I had an Ubuntu
12.04 installed with the same raid configuration:

What could be the problem?
I have another mdadm raid5 array that used to have XFS and gave the same
errors. I use it for backup and noticed that each backup from the main
array to the second one used to take a long time and gave these errors. I
switched from XFS to ext4 and not only did the errors go away
(obvisouly...) but the backup time went down from almost 23 hours to 1 hour!
Thanks,
Tal
