Driver: MVSAS

After years of development the MVSAS driver is still not suitable for
production use.  It is the cause of your problems here.  Any board using
the Marvell SAS chips is not suitable for use with Linux at this time
due to the poor driver quality.  These boards work fine under Windows
apparently.

Yes, I can help.  Replace the HighPoint boards with LSI 9211-8i boards
and everything should work fine, barring any compatibility issue with
the Tilera platform.
