btrfs raid10 setups cause the hardware reset to happen very frequently.
I have a eSATA enclosue (SansDigital) that has two eSATA ports and
contains 2 banks of 4 drives. 4 per eSATA port (port multiplier).  I
encounter no problems when using RAID1 with BTRFS across 8 drives.
However, when I use the  btrfs balance start -dconvert=raid10
-mconvert=raid10 to convert the set of 8 drives from a RAID1 to a
RAID10, it all falls apart with SATA hardware resets.  I am guessing
that the btrfs driver sits above all this and that the error is in the
SATA code and not the btrfs code which relies on it.
