Unfortunately I do not know the specifics, just that this is what's done in Adaptec's driver. There is some speculation it may be related to command timeouts observed with the latest series of controllers. In any case the change is part of a larger project to sync the in-tree driver with Adaptec's version. I have one report so far -- a PERC3 running firmware 2.7-1 BUILD 3170 works with this change. - EdReceived on Fri Feb 20 2009 - 14:36:13 UTC
