LSI2008 controller clobbers first disk with new LSI mps driver

[Jason Wolfe]

Kashyap,

Ah a response from LSI, that's a pleasant surprise :)  Everything you've
stated looks correct to me, the FreeBSD developed driver that has been
replaced by the LSI driver has no issues with either firmware.  Your likely
aware, but just to confirm, here is the history of the 3 various LSI
drivers that have the issue on the 10.00.02.00 FW:

11.00.00.00 - binary driver I had received from you guys in mid  2011,
mpslsi.ko, one for each 7.2-RELEASE and 8.2-RELEASE

11.255.03.00-fbsd - initial LSI driver committed to 8-STABLE on 2/2, r230922

13.00.00.00-fbsd - commited to 8-STABLE on 2/14, r231680

I have about 40 boxes with the 10.00.02.00 FW I've tested, so I'm fairly
certain it's not bad hardware or a fluke.  You guys haven't seen anything
like this in house?  I'd hate to hear I have to update the FW on these
boxes as they are all quite a ways from me, though it seems there is some
way to work around the behavior in the driver as the FreeBSD one does?  I
have a few of these boxes out of service so I'm game to try some things out
should that help.

Thank for the response,
Jason
