Subject: [PATCH 1/1] cciss: 2nd resubmit: add delay into kdump reset 

PATCH 1 of 1

From: Mike Miller <mike.miller@...com>

cciss: add delay back to PCI Power Management reset

When we change states from D0 to D3Hot and back to D0 we need a small delay.
Otherwise we may think the board has failed to reset and we bail. This
change affects the Smart Array P600.

Please ignore the previous patch that did this. I made it against the wrong
code base resulting in an offset. My apologies.

Another submission. I don't see this patch in the mailing list archives. I
only see the first submission which had an offset.
