Not sure what to make of this.  I've tested a lot of svn revisions of
the thunderbolt code, but nothing looks obvious. =20

When I use a single drive in "SYSPD" mode on a Dell H310 (falcon or
skinny drake) I get a /dev/mfisyspd0 device.  The JBOD mode *seems* to
work just fine as long as I don't do multiple things at once to it, e.g.
single user fsck works, but multiuser things die.

I get a failure case that emits errors such as:

g_vfs_done():error 27 in callback
mfisyspd0p2[READ(offset=3D7176192, length=3D425984)]mfisyspd0: hard error
error =3D 5
cmd=3Dread 15360-16383
error 27 in callback
g_vfs_done():mfisyspd0: hard error mfisyspd0p2[READ(offset=3D7602176,
length=3D524288)]cmd=3Dread error =3D 5
16384-17407
error 27 in callback
g_vfs_done():mfisyspd0: hard error mfisyspd0p2[READ(offset=3D8126464,
length=3D524288)]cmd=3Dread error =3D 5
14560-15359

g_vfs_done():mfisyspd0: hard error mfisyspd0p2[READ(offset=3D7192576,
