With respect to:
It would appear that it's unsafe to carry out ATA-passthrough operations
on SAS5* and SAS6* controllers (1068 / 1068E and others).
This definitely affects smartctl, and I'm assuming it has the potential
to impact operations such as drive firmware updates - locking up the
controller during a firmware update seems like it could be a Bad Thing.
Could someone at Dell take a look at this issue and see if their Linux
firmware update packages could be impacted? If they are impacted, I
guess they should be withdrawn until a workaround can be put in place...
