Hi,
I have a 8 drive md-raid6 + dm-crypt with xfs on top.
When trying to mount using 3.10-rc5 (ubuntu mainline ppa) I get the
following kernel bug:

3.10-rc4 has the same issue. I have not tried any earlier 3.10 kernels
The system mounts fine using 3.9.5 (also ubuntu ppa)
If I can provide any other info to help, please let me know.
